Processing-microstructure relationships in ferrous alloys via mixed powder laser powder bed fusion

Three different approaches to control the phase formation in powder bed fusion - laser beam (PBF-LB) printing using a powder mixture of duplex stainless steel (DSS) 2507 and austenitic stainless steel 316 L were examined: (i) in situ solid state reheating, (ii) utilization of an island scan strategy, and (iii) switching process parameters between layers of a build. Analytical modeling was used to determine the time-temperature profiles during each of these processes, and was combined with thermodynamic simulations through Thermo-Calc to predict and explain the phase formation measured experimentally. It was found that the reheating from additional layers was critical to the nucleation of austenite, even with the increased Ni content in powder mixtures. This was evident in the island scan strategy prints where the corners of the islands showed significantly less austenite (∼45%) as compared to the centers of the islands (∼96%), as well as in the multi-layer samples where alternating laser power for fixed chemical composition of powder mixture resulted in varying content from ∼75% (lower power) to ∼90% (higher power). Additionally, in situ reheating using a lower power laser was capable of minimally increasing the austenite content layer-by-layer, by raising the temperature of the layer above the nucleation temperature of austenite. These results showcase the capability of PBF-LB to manipulate phase structure in ways not possible through traditional manufacturing techniques, as well as the ability of Thermo-Calc to accurately predict the trends observed that can be applied to other alloy systems.

Study of Lactobacillus plantarum coated with Tremella polysaccharides to improve its intestinal adhesion.

The adhesion of probiotics to the intestine is crucial for their probiotic function. In previous studies, Tremella polysaccharides (TPS) (with sodium casein) have shown the potential to encapsulate probiotics and protect them in a simulated gastrointestinal tract. This study explored the effect of TPS (with sodium casein) on the adhesion of probiotics. Lactobacillus plantarum was coated with TPS and sodium casein in different proportions, and was freeze-dried. The rheological properties of the mixture of probiotics powder and mucin solution were determined by static and dynamic rheological analysis. Aqueous solutions of probiotic powder and mucin mixture exhibited pseudoplastic fluid rheological properties. The higher the proportion of TPS content, the higher the apparent viscosity and yield stress. The mixed bacterial powder and mucin fluid displayed thixotropy and was in accordance with the Herschel-Bulkley model. The TPS increased the bio-adhesive force of the probiotic powder and mucin. When using TPS as the only carbon source, the adhesion of L. plantarum to Caco-2 cells increased by 228% in comparison with glucose in vitro. Twelve adhesive proteins were also detected in the whole-cell proteome of L. plantarum. Among them, ten adhesive proteins occurred abundantly when grown with TPS as a carbon source. Tremella polysaccharides therefore possess probiotic properties and can promote the intestinal adhesion of L. plantarum. © 2024 Society of Chemical Industry.

Hf-W dating of zircon in mesosiderite with high-pressure sintered standard

New standard zircons applicable to in situ analysis of Hf/W ratio by Nanoscale secondary ion mass spectrometer (NanoSIMS) were prepared and applied to Hf-W dating of a differentiated meteorite classified as mesosiderite. The standard zircons were synthesized by high-pressure experiment from starting materials which were mixture of hafnium oxide, tungsten oxide and high-purity zircon powder. The mixed powders were stirred and pulverized by a high-energy ball mill. They were then sintered at 1000 °C and 6 GPa using multi-anvil apparatus. Homogeneity of Hf/W ratios of synthesized zircons was examined by SEM–EDS, EPMA, and Laser Ablation Inductively Coupled Plasma Mass Spectrometer (LA-ICPMS). Hf/W ratios of the same zircons were measured by a NanoSIMS with 2 nA oxygen primary beam and mass resolving power of 10,000. The relative sensitivity factor (RSF) of Hf/W ratio was determined by comparing zircon data measured by LA-ICPMS and NanoSIMS. Observed RSF (Hf/W) of zircon is 0.585 ± 0.180 (hereafter all error 2σ) consistent with 0.855 ± 0.468 of previous work within experimental error margin. The value is higher than observed RSF of glass matrix, 0.301 ± 0.062, and significantly higher than glass data of 0.21–0.22 in references. Based on the RSF, the Hf/W ratios of zircons extracted from mesosiderite “Asuka 882,023” were measured together with W isotopic compositions by NanoSIMS. Observed data in 180Hf/186W–182W/186W diagram are fitted by a straight line, yielding a slope (182Hf/180Hf) of 8.19 ± 3.50 × 10–6. This slope is converted into an absolute zircon Hf-W age of 4536.5+4.6–7.2 Ma using the age anchor of CV3 chondrite. This age agrees well with a reference value of 4532.0+11.4–20.8 Ma.

Effect of phase evolution and pyroplastic formation behavior on glass-ceramic foam derived from silicomanganese slag and feldspar tailings

Utilizing solid waste to produce foam material has become a significant direction in resource recycling. This study focuses solely on using silicomanganese slag and feldspar tailings as raw materials, utilizing a powder sintering process to produce autocatalytic foaming glass–ceramic foam. We formulated four mix ratios based on the compositional characteristics of the silicomanganese slag and feldspar tailings. The study then explored the evolution of phase formation and macroscopic pore morphology under varying preparation temperatures. Moreover, through multi-phase co-melting experiments, this work unveiled the high-temperature molten mass generation mechanism between silicomanganese slag and feldspar tailings. Our findings reveal that the glass melt generated from silicomanganese slag particles and the 'solid–liquid erosion behavior' of feldspar particles play pivotal roles in the formation of high-temperature co-melt substances. As the sintering temperature increases, the mixed powder exhibits three different states of high-temperature molten mass, which are the reasons for the evolution of the macroscopic pore structure. It is suggested that the addition of silicomanganese slag should be less than 50 %, and the heat treatment temperature should be below 1145 °C in preparing glass–ceramic foam with silicomanganese slag and feldspar tailings. The sample with 40 % silicomanganese slag and 60 % feldspar tailings, treated at 1140 °C, yielded glass–ceramic foam with a compressive strength of 1.68 MPa, apparent density of 0.279 g/cm3, porosity of 81.7 %, and thermal conductivity of 0.074 W·m−1·K−1. In summary, this study provides a novel approach for the high-value utilization of silicomanganese slag and offers an economical route for developing lightweight, eco-friendly structural materials.

Fabrication of homogenous Sb2(S,Se)3 solar cells by close space sublimation using a single alloyed powder source

Sulfoselenide Sb2(S,Se)3, as a potential light-harvester, possesses a flexibly tunable bandgap of 1.1–1.7 eV to match solar radiation spectrum. However, the preparation of a homogenous Sb2(S,Se)3 film is still challenging due to the different growth kinetics in sulfide and selenide compound, which consequentially leads to phase separation, lattice disorder and unfavored band level. This dilemma also occurs in the simple and well-established close space sublimation (CSS) method, and poses a devastating carrier recombination in Sb2(S,Se)3 solar cells. Herein, alloyed powders of Sb2(S,Se)3 are exquisitely synthesized by a thorough gas-solid reaction, delivering a uniform and single phase composition distribution as well as finely-tunable S/Se ratio. Compared with a physically mixed powder source (Sb2S3/Sb2Se3), this alloyed Sb2(S,Se)3 source allows for the fabrication of a homogeneous Sb2(S,Se)3 thin film by CSS, rendering improved (hk1) orientation, dense morphology, a more consistent longitudinal S/Se ratio, and enhanced energy level arrangement. These advancements contribute to enhance carrier transport and reduce carrier recombination. As a result, the efficiency of the solar cell is remarkably boosted from 2.59% to 5.46%, which is among of the highest PCE of full-inorganic Sb2(S,Se)3 devices fabricated through the CSS method.

Effect of LLZTO Tablet Pressing Process on Electrochemical Properties of Button Batteries

AbstractThe garnet‐type Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a widely studied solid‐state electrolytes (SSEs) due to its high ionic conductivity and electrochemical stability. However, the conventional preparation process of LLZTO electrolyte tablets has encountered several issues such as powder embedment in the mold gaps and inadequate bonding between powders, leading to fragile electrolyte tablets that are prone to cracking. In this study, the effects of LLZTO electrolyte tablet pressing process parameters, including mixed powder content, polyvinyl alcohol (PVA) content and cold pressing pressure, on the electrochemical properties of button cells were investigated. The results indicated that the produced solid‐state electrolyte tablets with high quality, low interfacial resistance and low surface passivation layer (Li2CO3) content was obtained by using 0.8 g of mixed powder content, 0.7 g of PVA content and 20Mpa pressure. The interface resistance decreased from 2927.1 Ω to 1069.7 Ω under these conditions. Additionally, the Li symmetric cell treated with adhesive exhibited stable cycling for over 400 hours at 25 °C under a current density of 0.1 mA ⋅ cm−2.

A functional and probiotic approach: mixed fruit juice powder with addition of lactobacilli

The aim of this study was to evaluate changes in a mixture of acerola and ciriguela juice (40/60%, respectively) and the juice mixture supplemented with Lactobacillus rhamnosus LPAA 01, L. casei LPAA 02, and L. plantarum LPAA 03, ratio 1:1, both powders obtained by spray drying, during storage. The stability of acerola and ciriguela mixed powder without the addition of microorganisms was evaluated for 90 days at 25°C in different water activities (Aws) (0.11, 0.23, and 0.34). Aw that most effectively maintained the stability of mixed powdered juice was used for the evaluation of the fermented mixed juice powder containing probiotics for 45 days at 5 and 25°C, respectively. Samples were characterized by physicochemical properties, bioactive compounds, and cell viability. The physicochemical properties of the powdered mixed juice without the addition of probiotics remained stable when stored at 25°C at an Aw of 0.11 for 60 days. Ascorbic acid, carotenoids, and total phenolics showed favorable characteristics for the commercialization and bioactive properties of the powders, with potential use as functional ingredients in food. Probiotic powders showed viable cell counts above 6.0 log colony-forming units (CFU)/g after storage for up to 20 days at 5°C and up to 14 days at 25°C.

Microstructure and properties of bilayered B4C-based composites prepared by hot-pressing

Bilayered B4C-based composites were prepared by hot-pressing method. One layer was a B4C ceramic layer using C and Ti powders as sintering assistants. The other layer was a B4C ductile layer named as BST layer, in which TiC, Si and Ti mixed powders were added to synthesize Ti3SiC2 phase to improve toughness of B4C. Although XRD results showed that no Ti3SiC2 was found in the BST layer, SEM and EDS analyses proved that trace amount of lamellar Ti3SiC2 structure was observed under high magnification fractographs in the BST layers with additive contents (x) equal to 30 and 40 wt%. Both the flexural strength and fracture toughness of the bilayered B4C-based composite increased with the increase in the amount of additions in the BST layer, reaching optimum values of 550 MPa and 6.6 MPa m1/2 at x = 40 wt%, respectively.

식물 추출물 혼합 분말이 C2C12 세포 내 분화 및 산화적 스트레스 유발 세포사멸 조절에 미치는 효과

This study evaluated the differentiation and protective effects of mixed plant-extract powder in C2C12 muscle cells. Cells were differentiated into myotubes in 2% horse serum (HS)-containing medium with mixed plant-extract powder (MPEP) for 6 days. Treatment with MPEP increased the expression of myogenin and myosin heavy chain (MHC) protein in cells compared with non-treated cells. Differentiated cells were pretreated with MPEP, and hydrogen peroxide (H2O2). Our results revealed that treatment with MPEP before H2O2 treatment increased cell viability and decreased H2O2-induced lactate dehydrogenase (LDH) and creatine kinase (CK). In addition, MPEP attenuated H2O2-induced upregulation of Bax, downregulation of Bcl-2, and activation of caspase-9 and -3. These results suggest the MPEP can stimulate C2C12 muscle cell differentiation into myotubes and observe the protective effect of mixed plant-extract powder against muscle oxidative stress. In conclusion, MPEP may be useful as a prevention and treatment material for skeletal muscle disease caused by age-related diseases.

Fabrication, microstructure, and mechanical properties of novel three‐layer structured bionic ceramic cutting tools

AbstractCeramic cutting tools have low fracture toughness owing to brittleness. To improve the fracture toughness and flexural strength of ceramic cutting tools, the growth model of SiCw during the sintering process was established by the laminated structure and anisotropy of growth of bionic shells. Furthermore, a theoretical model of sintering parameters and total fracture toughness was achieved. Then, the dispersion process of SiCw was improved to enhance the homogeneity of the mixed powders further. Finally, a novel three‐layer structured bionic ceramic cutting tool was fabricated by hot‐pressing. The effects of sintering temperature, holding time, and sintering pressure on the mechanical properties and microstructure of bionic ceramic cutting tools were investigated. The results showed that the flexural strength (three point bending), fracture toughness (indentation method), and Vickers hardness of the three‐layer structured bionic ceramic cutting tool with excellent dispersed were 735 ± 34 MPa, 5.68 ± 0.06 MPa·m1/2, and 19.66 ± 0.12 GPa, respectively. The microstructure of the fracture revealed that the fracture mechanism of the bionic ceramic cutting tool was a mixture of intergranular fracture, transgranular fracture, whisker pull‐out, whisker fracture, forked crack, crack deflection, crack bridging, zig‐zag crack, and crack termination. The accuracy of the total fracture toughness model was reliable.

Investigation and Optimization on Parameters of Gas Additive Powder Mixed Near Dry –EDM (GAPMNDEDM) by using Taguchi based- Grey Relational Optimization

The Gas Additive Powder Mix near Dry Electric Discharge Machining (GAPMND-EDM) serves a manufacturing purpose, specifically for cutting hard materials. This involves the removal of material from a workpiece via fusion, ablation, and evaporation caused by the heat energy generated through electric sparks during energy supply. The process offers several advantages in terms of performance and characteristics. This research project aims to optimize key process parameters, including material removal rate, surface roughness, residual stresses, and microhardness. The study employs a methodology that combines the standard deviation-based objective weighting method with GRA (Gray Relational Analysis) optimization to enhance the hybrid GAPMND-EDM process when applied to EN-31 material. Experimental runs were conducted to evaluate the impact of various input factors, such as pulse-on time, discharge current, dielectric fluid pressure, and metallic powder concentration. The taguchi-based GRA method was utilized for this purpose, and the experimental design followed an L-27 orthogonal array with the assistance of Minitab-19 software. A total of 27 experiments were performed, encompassing diverse combinations of process parameters. Subsequently, an ANOVA (Analysis of Variance) was executed to analyze the influence of pulse-on time, discharge current, dielectric fluid pressure, and metallic powder concentration on Material Removal Rate (MRR), Surface Roughness (SR), Residual Stress (RS), and Microhardness (MH). The result shows the optimal combination of parameters, denoted as A2B2C2D1, was identified as the preferred configuration.

Microstructural development and oxidation resistance of MSi2-type multicomponent silicide coatings on Nb alloys by spark plasma sintering

MSi2-type multicomponent silicide coatings were prepared on Nb alloys by spark plasma sintering using mixed powders of Mo, Ta, W, Zr, Ti and Si. The coatings were composed of thick outer layers and thin inner layers (interdiffusion zone). A two-phase structure consisting of C11b (Mo,Ta,W,Ti)Si2 and C40 (Ti,Ta,Zr)Si2 was observed in the outer layers of all the coatings sintered for holding times ranging from 15 s to 5 min, but the distribution of these elements in each phase gradually became uniform with increasing holding time. The coatings demonstrated excellent protection during oxidation at 1300 °C for 100 h, and a continuous dense oxide scale mainly composed of ZrSiO4 and SiO2 was generated. The alternation of heating and cooling during oxidation caused cracks to appear at the interface between the outer layer and inner layer due to a mismatch of thermal expansion coefficients. However, crack extension was observed only along the inner layer toward the interior due to the multicomponent structure of the outer layer of the coating. The microstructural development and oxidation behavior of the coatings were discussed.

Simultaneous enhancement in mechanical and physical properties of graphene-oxide-reinforced Al matrix composites by trace-Mg-alloying strategy

This paper proposes a trace-Mg-alloying strategy to fabricate high-performance graphene oxide (GO)-reinforced Al metal matrix composites (MMC). A minute quantity (0.4 wt%) of elemental Mg was introduced in Al–Si alloy powders. Individual GO nanosheets were uniformly decorated onto the surface of the AlSiMg particle through electrostatic attractions via hetero-agglomeration. A GO network was formed at the primary boundaries of AlSiMg particles through spark plasma sintering of GO/AlSiMg mixed powders. In this process, elemental Mg reacted with the oxygen atoms within GO nanosheets, resulting in the in situ production of high-quality reduced GO. Subsequent hot extrusion disrupted the GO network owing to the metal plastic flow, causing the GO nanosheets to realign in a single direction. Consequently, the tribological behavior, tensile response, and thermal and electrical conductivities of the GO/AlSiMg composites were simultaneously enhanced. Hot extrusion led to stretching of the overlapping GO nanosheets and increased surface contact area of AlSiMg powders. Thus, the extruded samples exhibited peak electrical conductivity at 0.2 wt% GO, whereas the sintered samples demonstrated peak thermal conductivity at 0.1 wt% GO. Overall, the findings of this study highlight the potential of merging trace powder alloying and powder metallurgy techniques to create multifunctional nanocarbon/MMCs without a trade-off between mechanical and physical performance.

Strengthening of Mullite Ceramics with Silver Reinforcements

Mullite-based composites reinforced with silver particles were obtained by powder techniques. Composites were sintered after an intense mixing of the precursor powders. It was found that additions of silver have a strong effect on the mechanical properties, since fracture toughness was increased up to 350%. The microstructure of composites presents grains with flakes morphology.

Effect of Process Parameters on the Microstructure and Wear Resistance of Fe3Al/Cr3C2 Composites

In this paper, a brake cylinder coating comprising a composite material of an Fe3Al and Cr3C2 mixed powder was prepared by adding laser cladding onto carbon structural steel. We studied the influence of process parameters on the microstructure and tribological properties of the cladding materials using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and 3D white light interferometer and wear tests. The influence of different processes on the morphology of the carbide strengthening phase was found to be relatively small with a Cr3C2 content of 15 wt.%. The carbides mainly exhibited a network structure in each group of cladding layers. The area of the network strengthening phase varied under different processes. Of the cladding layers formed with different processes, the scanning speed of the 0.003 m/s cladding layer had the lowest wear rate. When the laser power was too low or the powder feed rate was too high, unmelted Cr3C2 particles could be found in the cladding layer. During the wear process, the particles peeled off, causing severe abrasive wear. When the powder feeding rate was too low, more materials in the base material entered the cladding layer. This made the composition of the cladding layer similar to that of the grinding material, resulting in severe adhesive wear.

Cr-rich structure evolution and enhanced mechanical properties of CoCrFeNi high entropy alloys by mechanical alloying

Mechanically-alloyed CoCrFeNi high entropy alloys (MA-HEAs) show better mechanical properties than as-cast HEAs. However, the limited amount of powder milled in one-milling cycle creates a challenge in larger-scale applications. The low ball-to-powder ratio (BPR) milling used to increase powder yield resulted in the formation of Cr-rich second phases in the face-centered cubic matrix. To overcome the above issues, in this work, with a low BPR of 5:1, four different processes were analyzed: quicker milling intervals, higher milling speed, and the pre-alloying of Cr and Ni. All parameters mentioned before were used and tested together in the fourth sample. Samples were consolidated by spark plasma sintering technique. Microstructural characterization was made on a Scanning Electron Microscope equipped with EDS and EBSD detectors and a Transmission Electron Microscope. X-ray diffraction was employed to develop the structural evolution of powders sintered and annealed samples. The global hardness was measured using microhardness tests, while the nanohardness tests helped us correlate the evolution of secondary phases with their mechanical properties. The results show that pre-alloying elements with the lowest diffusion coefficient before the main milling process might be an attractive strategy to improve productivity and optimize microstructure without limiting the efficiency of low BPR MA-HEAs. The results described below demonstrate the promising perspective for the implementation of powder metallurgy techniques in a mass scale production as low BPR is essential for numerous applications like aerospace industry, car engines and medicine, where improved productivity of powder mixing is mandatory.

Study on the separation and mixing laws of wide-grained dense medium in vibration separation fluidized bed

Vibro-fluidized dry coal beneficiation involves the unavoidable mixing of −1 mm coal dust into a fluidized bed, which compromises the stability and homogeneity of the bed density and reduces the effectiveness of fine-grained coal separation. To understand the features of coal powder separation and mixing (-1 mm) in a vibrating fluidized bed, as well as to achieve a uniform and stable bed density, a wide-grained dense medium consisting of −1 mm coal dust and 0.3–0.15 mm magnetite powder was homogeneously mixed in this work. The degree of density separation in the entire bed and the local mixing properties of the wide-grained dense medium were examined. It was discovered that when low vibrational energy was introduced at the same air velocity, particle separation was enhanced compared to the usual fluidized bed. Small bubbles were found to ensnare fine coal dust and migrate upwards, increasing the density separation. The introduction of high vibrational energy led to particle disorder within the bed and an increase in the level of particle mixing. The beneficial effects of the vibration on the bed diminished when the air velocity was gradually increased under the specified vibration conditions. This caused large bubbles to develop more frequently, which increased particle mixing. The 1–0.5 mm fine-grained coal exhibited the best mixing state; it was less affected by variations in air velocity and vibration levels, whereas the −0.5 mm coal dust was more affected by each variable. Furthermore, the particle system achieved a wide range of air velocity regulations without a significant segregation state change under the vibration conditions of f= 25 Hz and A=1 mm and f= 25 Hz and A=2 mm.

Wear behavior and corrosion resistance of laser-clad Ni60-1 % carbon nanotubes coating

Carbon nanotubes (CNTs) can improve the performance of composite coatings as reinforcing powders due to their three-dimensional (3D) tubular structure and good self-lubricating properties. Unfortunately, CNTs are difficult to mix uniformly with other powders due to their extremely light mass and fragile microstructure. Therefore, in this study, the alcohol-stirring mixing method was used for powder mixing. The results showed that Ni60 powder and 1 wt% CNTs were mixed homogeneously by this method, and large-area CNTs deposition was achieved on the surface of Ni60 powder. The properties of the Ni60/CNTs coatings fabricated by laser cladding (LC) were examined. The microstructure of the Ni60/CNTs coating was refined, and M23C6 carbides were generated. Compared with the Ni60 coating, the microhardness of the Ni60/CNTs coating increased by 41.6 %, and the wear rate decreased by 76.76 %. The improvement is mainly due to the excellent self-lubricating properties of CNTs and their tubular structure, which improves the friction behavior of the coating. In addition, the refinement of microstructure and the generation of C23C6 carbides also play an enhanced role. The bridging of the tubular structure of CNTs and the filling effect of carbides resulted in improved corrosion resistance of the Ni60/CNTs coatings.

Оптимизация режимов селективного лазерного плавления порошковой композиции системы AlSiMg

Introduction. New aluminum-based powder systems are currently being developed for additive manufacturing. The scientists' work is aimed at comprehensive studies of powder production, optimization of conditions for alloy production and formation of three-dimensional specimens with minimal porosity and absence of cracking during selective laser melting. The purpose of this work is the synthesis of an almost spherical Al-Si-Mg composite powder (91 wt. % Al, 8 wt. % Si, 1 wt. % Mg) from aluminum powder PA-4 (GOST 6058-22), silicon powder (GOST 2169-69) and magnesium powder MPF-4 (GOST 6001-79), which were not originally intended for selective laser melting technology. The work also provides for the optimization of selective laser melting modes to obtain an alloy and form three-dimensional specimens with minimal porosity and no cracking. To create a powder composition, powders ranging in size from 20 to 64 μm were selected by sieve analysis and subjected to mechanical mixing in a ball mill in a protective argon medium for one hour. The research methods are methods of X-ray diffraction and X-ray phase analysis, transmission electron microscopy, mechanical tests of microhardness. Studies of the powder composition after mechanical mixing showed that the mixed powder of aluminum, silicon and magnesium is a conglomerate of particles of spherical, oval and irregular shape. Results and discussions. The optimal modes for obtaining a specimen with a minimum porosity of 0.03 % and a microhardness of 1,291 MPa are selective laser melting modes: P = 90 W, V = 225 mm/s, S = 0.08 mm, h = 0.025 mm. The conducted research shows the possibility of synthesizing products from metal powders that are not adapted to processing by selective laser melting and obtaining an alloy with new mechanical properties during laser action.

Mechanical and tribological performance of copper matrix self-lubricating composite prepared by resonant acoustic mixing powder

CuNi-WS2 self-lubricating composites with 10 wt% WS2 were fabricated by combining resonant acoustic mixing (RAM) powders and pressureless sintering in an H2 atmosphere. The influence of acceleration, a critical process parameter of RAM, on the microstructures, mechanical and tribological performance of the composites were investigated, then the mechanism of acceleration on the performance of composites was discussed based on the analysis of the morphology and dispersion of WS2. The composite exhibits optimal mechanical and tribological properties at an acceleration of 70 g, with a bending strength of 231 MPa, and the friction coefficient and the wear rate are 0.243 and 9.26 × 10−5 mm3/N·m, respectively. WS2 is primarily dispersed through the composite as small clusters and tiny particles at an acceleration of 70 g. It not only promotes the interfacial reaction of WS2 to generate hard W particles, improving the strength of composites, but also facilitates the formation of compact tribo-film, avoiding massive fractures caused by the fragmentation of large WS2 agglomerations.
