TiO2-BN/CNTs coating with radiative cooling and reduced friction

To date, the demand for electronic packaging materials with combined highly efficient heat dissipation and low friction attracts intensive attention. There have been hardly any reports of coatings that provide simultaneous radiative cooling, thermal conduction, and friction reduction properties. In the present work, a novel biomimetic nanocomposite coating is gown on the titanium alloy substrate. The coating consists of a TiO2 ceramic layer adorned with hemispherical protrusions and is enriched with hexagonal boron nitride (h-BN) flakes and CNTs on the surface. The optimal microstructures are determined through Finite Difference Time Domain (FDTD) simulation calculations and then prepared using plasma electrolytic oxidation (PEO). The results show that the hierarchical micro/nanostructures enable the coating to achieve an infrared emissivity of ∼ 0.9 within the 3–14 wavelength range, whilst h-BN and CNTs contribute to the thermal conduction of the TiO2-BN/CNTs ceramic coating. The advantage of the biomimetic nanocomposite coating over the bare titanium alloy is that the coating facilitates a reduction in the equilibrium temperature of a 5 W LED by around 21.5 °C. In addition, the coating exhibits outstanding friction reduction performance with a low friction coefficient (COF) of 0.15 over a sliding distance of 94.2 m, benefitted from the lubrication effect of h-BN and CNT. This work introduces a straightforward and environmentally friendly approach to fabricating bifunctional thermal regulation materials.

One-Pot Synthesis of Alkyl Functionalized Reduced Graphene Oxide Nanocomposites as the Lubrication Additive Enabling Enhanced Tribological Performance.

Recently, aiming for the enhanced dispersibility of graphene-based nanomaterials in lubricating oil matrices to serve as highly efficient lubricant additives, numerous modification approaches have been extensively studied. However, these previous modification routes usually involve a tedious multistep modification process or multitudinous toxic reagents, restricting their extensive practical application. In this work, novel graphene oxide (GO) nanoadditives (RGO-g-BO) featuring excellent durable dispersion capability and remarkable tribological performance were successfully prepared via an environmentally friendly one-step approach consisting of surface grafting of long-chain bromooctadecane (BO) and in situ chemical reduction. Benefiting from the greatly improved lipophilicity (resulting from the introduction of hydrophobic long-chain alkane groups and chemical reduction), along with the miniaturization effect, RGO-g-BO exhibits superior long-term dispersion stability in the finished oil. Moreover, the tribological properties results demonstrated that the finished oil filled with RGO-g-BO nanolubricants achieved an outstanding friction-reducing and antiwear performance. Particularly, under the optimum content of RGO-g-BO (as low as 0.005 wt%), the friction coefficient as well as the wear volume of the composite finished oil were greatly reduced by 13% and 53%, respectively, as compared with nascent finished oil. Therefore, in view of the advantages of low-cost, one-step facile synthesis, desirable dispersion capability, and remarkable tribological performance, RGO-g-BO holds great prospects as a highly efficient lubrication additive in the tribology field.

Optimization and tribological performance of PEEK based composite coatings reinforced with PTFE for friction pairs of aviation hydraulic pumps

In this study, polyetheretherketone (PEEK) based composite coatings reinforced with polytetrafluoroethylene (PTFE) were applied to copper-steel bimetallic plates. The impact of process parameters on the tribological properties of the coatings was investigated. The results indicated that the optimized PTFE/PEEK2.2 coating exhibited commendable friction reduction and wear resistance performance when subjected to aviation kerosene lubrication. It was observed that the hot-pressing temperature has the most significant influence on the bearing capacity and wear rate of the coatings. In contrast, the hot-pressing pressure primarily affects the average friction coefficient. The primary wear mechanism observed in these coatings is adhesive wear. These findings suggest promising application prospects for the composite coatings in aviation hydraulic pumps, underscoring their potential to significantly improve overall performance.

Large eddy simulation of boundary layer combustion of hydrogen and hydrocarbon fuel films in a modeled scramjet combustor

Supersonic fuel film cooling is a promising way to simultaneously reduce the severe wall heat and friction load of the internal passage in a scramjet engine when operating at hypersonic conditions. Large eddy simulations were performed to investigate the cooling and wall friction characteristics of hydrogen and hydrocarbon films under inert and reactive circumstances. The results show that the essential difference of the turbulent state in the mixing layer contributes to the totally different behaviors of the cooling and wall friction reduction performances of the two fuel films. The turbulent transport processes between the hydrogen film and the mainstream are much weaker as compared to the case of hydrocarbon film, making inert hydrogen rather superior in cooling and friction reduction applications. Besides, the increase of wall temperature for hydrogen film under the inert case is mainly driven by the loss of hydrogen with high heat capacity instead of by direct heat addition. However, the film cooling performance severely deteriorates when the hydrogen film burns due to presence of severe heat release sources near the wall. On the other hand, combustion of hydrocarbon film in the boundary layer can remarkably improve its originally barely-satisfactory cooling and friction reduction performance to the level comparable to that of hydrogen film, due to the suppression of turbulent transport processes in the mixing layer and presence of heat absorption sources near the wall. Overall, the hydrogen film is more advantageous in friction reduction, while the hydrocarbon film is more suitable for cooling.

Unraveling Water-Based Lubrication with Carbon Dots of Asphaltene Origin.

Despite the lower toxicity of water-based lubricants over nonrenewable petroleum-based analogues, they face challenges in achieving widespread adoption due to low stability and inadequate friction-reduction performance. To address this, a cost-effective nanoadditive is synthesized by expansive oxidation of asphaltenes to create biocompatible asphaltene-derived carbon dots [(ACDs); 5 nm]. These ACDs exhibit excellent water redispersibility, promoting long-term friction reduction and marking the first use of an asphaltene-based system for friction reduction in water or oil. Even at low loadings (0.2-4.0 wt %), ACDs significantly reduce friction on steel surfaces (>54%) with tribofilm stability surpassing pristine carbon dots, typical carbon-based graphene quantum dots, and inorganic nanomaterials (commercial 5 and 20 nm silica). The ACDs' attributes include high negative zeta potential, considerable water uptake, varied functional groups, biocompatibility, and a nanodisc shape conducive to stable tribofilm formation through effective particle stacking. The scalable synthesis, high yield, and impressive water redispersibility of ACDs position them favorably for commercial water-based lubrication.

Nanobiolubricant grinding: a comprehensive review

AbstractMinimum quantity lubrication (MQL), which considers the cost, sustainability, flexibility, and quality, has been actively explored by scholars. Nanoadditive phases have been widely investigated as atomizing media for MQL, aimed at enhancing the heat transfer and friction reduction performance of vegetable-oil-based biolubricants. However, the industrial application of nano-enhanced biolubricants (NEBL) in grinding wheels and workpiece interfaces as a cooling and lubricating medium still faces serious challenges, which are attributed to the knowledge gap in the current mapping between the properties and grindability of NEBL. This paper presents a comprehensive literature review of research developments in NEBL grinding, highlighting the key challenges, and clarifies the application of blind spots. Firstly, the physicochemical properties of the NEBL are elaborated from the perspective of the base fluid and nanoadditive phase. Secondly, the excellent grinding performance of the NEBL is clarified by its distinctive film formation, heat transfer, and multiple-field mobilization capacity. Nanoparticles with high thermal conductivity and excellent extreme-pressure film-forming properties significantly improved the high-temperature and extreme-friction conditions in the grinding zone. Furthermore, the sustainability of applying small amounts of NEBL to grinding is systematically evaluated, providing valuable insights for the industry. Finally, perspectives are proposed to address the engineering and scientific bottlenecks of NEBL. This review aims to contribute to the understanding of the effective mechanisms of NEBL and the development of green grinding technologies.

Study on friction reduction performance of granular flow lubrication during the milling of Inconel 718 superalloy

PurposeThe purpose of this study is to reveal the friction reduction performance and mechanism of granular flow lubrication during the milling of difficult-to-machining materials and provide a high-performance lubrication method for the precision cutting of nickel-based alloys.Design/methodology/approachThe milling tests for Inconel 718 superalloy under dry cutting, flood lubrication and granular flow lubrication were carried out, and the milling force and machined surface quality were used to evaluate their friction reduction effect. Furthermore, based on the energy dispersive spectrometer (EDS) spectrums and the topographical features of machined surface, the lubrication mechanism of different granular mediums was explored during granular flow lubrication.FindingsCompared with flood lubrication, the granular flow lubrication had a significant force reduction effect, and the maximum milling force was reduced by about 30%. At the same time, the granular flow lubrication was more conducive to reducing the tool trace size, repressing surface damage and thus achieving better surface quality. The soft particles had better friction reduction performance than the hard particles with the same particle size, and the friction reduction performance of nanoscale hard particles was superior to that of microscale hard particles. The friction reduction mechanism of MoS2 and WS2 soft particles is the mending effect and adsorption film effect, whereas that of SiO2 and Al2O3 hard particles is mainly manifested as the rolling and polishing effect.Originality/valueGranular flow lubrication was applied in the precision milling of Inconel 718 superalloy, and a comparative study was conducted on the friction reduction performance of soft particles (MoS2, WS2) and hard particles (SiO2, Al2O3). Based on the EDS spectrums and topographical features of machined surface, the friction reduction mechanism of soft and hard particles was explored.

Influence of cBN on the microstructure and tribology properties of (CoCrNi)94Al3Ti3 medium-entropy alloy coating prepared by high-speed laser cladding: The evolution and strengthening mechanism of cBN

Ceramic particle reinforced medium entropy alloys (MEAs) coatings have attracted considerable attention because of their excellent hardness and wear resistance. In this study, (CoCrNi)94Al3Ti3 MEA coating and (CoCrNi)94Al3Ti3-cBN MEA composite coating were prepared by high-speed laser cladding. The phase constituents, microstructure，hardness and wear mechanisms of the two coatings were investigated using XRD, Raman spectra, SEM, EDS, and TEM. Results show that (CoCrNi)94Al3Ti3 comprises only simple FCC phase because of the high-entropy effect. However, the addition of cBN transforms the phase from FCC to FCC + BCC, but also generates micron-scale TiN and CoCr, as well as nanoscale TiN and CrB. In addition, part of the cBN is converted to hBN with lubricating effect under high energy laser. As for the properties, compared with (CoCrNi)94Al3Ti3 coating, (CoCrNi)94Al3Ti3-cBN coating exhibits increased hardness by 2.2 times, increased wear resistance by 5.6 times, and decreased friction coefficient from 0.58 to 0.47. It is expected that this research will provide research ideas for the preparation coating of friction reduction and wear resistance performances on titanium alloy surfaces.

Preparation and tribological study of novel amide-based organic friction modifiers

We have synthesized two novel amide-based organic friction modifiers(OFMs), namely NIPAOA and NDEAOA, through the addition reaction of oleamine with N-isopropylacrylamide and N, N-dimethylacrylamide. The two OFMs exhibit good solubility in PAO6 base oil. Their tribological performance has been investigated using a line contact both individually and when compounded with the anti-wear additive zinc dialkyldithiophosphate (ZDDP) at temperatures ranging from 40 ℃ to 130 ℃. The results show that NIPAOA and NDEAOA form dual-site adsorption on the tribo-pair surface through the N and O atoms in the head group amide, resulting in the tribo-film exhibiting excellent friction-reducing performance in PAO6 across the temperatures. When compounded with ZDDP, they both exhibit effective synergistic friction-reducing effects, attributed to the formation of a unique tribo-chemical reaction film on the worn surface that contains almost no Fe and its compounds. The formation of the unique tribo-film is partly due to the continuous adsorption of free OFMs on the surface of the formed ZDDP tribo-film, providing a milder contact environment for the tribo-pair, allowing for the continuous polymerization of medium and long-chain zinc dialkyldithiophosphate (ZDDP) to ultimately form a uniform and flat tribo-chemical reaction film which interspersed with nitrogen-containing compounds. Even after long-term testing, the film maintains good stability and abrasion resistance, effectively synergizing friction-reducing and anti-wear properties.

In-situ synthesis and wear mechanism of Ni- based self-lubricating composite coating with a dense continuous metal sulfide layer prepared by laser cladding

The friction and wear of bearing cages, sealing rings and other transmission components working in harsh environments such as high vacuum and heavy load directly affect the operational stability and safety reliability of the equipment. Therefore, it is vitally important to improve the tribological properties of machine components. In this paper, NiCrBSi alloy coating, NiCrBSi-30 wt% WS2 coating and double-layer NiCrBSi-30 wt% WS2 coating were prepared on 38CrMoAl steel by laser cladding. The results show that a metal sulfide layer is formed on the double-layer NiCrBSi-30 wt% WS2 coating compared to NiCrBSi-30 wt% WS2 coating. The NiCrBSi-30 wt% WS2 coating consists of γ-(Ni,Fe) solid solution, (Fe,Ni)9S8, Cr7S8 and M7C3 phases. The metal sulfide layer consists of γ-(Ni, Fe) solid solutions, Fe3S4, CrxSy and M7C3 phases. The double-layer NiCrBSi-30 wt% WS2 coating is 4 mm thicker than the NiCrBSi-30 wt% WS2 coating. The average microhardness values of NiCrBSi coating, NiCrBSi-WS2 coating and double-layer NiCrBSi-WS2 coating are 412.6 ± 15.2HV0.3, 383.9 ± 14.5HV0.3, and 368.6 ± 13.3HV0.3, respectively. The average coefficient of friction of the double-layer NiCrBSi-30 wt% WS2 coating is 0.29, which is 37 % and 14.7 % lower than that of the NiCrBSi coating (0.46) and the NiCrBSi-30 wt% WS2 coating (0.34), respectively. The wear rate of the double-layer NiCrBSi-30 wt% WS2 coating is 1.51 × 10−5 mm3/(N·m), which is 47.6 % and 34.9 % lower than that of NiCrBSi coating (2.88 × 10−5 mm3/(N·m)) and NiCrBSi-30 wt% WS2 coating (2.32 × 10−5 mm3/(N·m)), respectively. Therefore, double-layer NiCrBSi-30 wt% WS2 coating has the best wear resistance and friction reduction performance at room temperature. A more continuous lubricating film was formed on the surface of the double-layer NiCrBSi-30 wt% WS2 coating, which explains its lowest coefficient of friction and wear rate.

Oil-soluble polymer brushes-functionalized nanoMOFs for highly efficient friction and wear reduction

Nanomaterials as lubricating oil additives have attracted significant attention because of their designable composition and structure, suitable mechanical property, and tunable surface functionalities. However, the poor compatibility between nanomaterials and base oil limits their further applications. In this work, we demonstrated oil-soluble poly (lauryl methacrylate) (PLMA) brushes-grafted metal-organic frameworks nanoparticles (nanoMOFs) as lubricating oil additives that can achieve efficient friction reduction and anti-wear performance. Macroinitiators were synthesized by free-radical polymerization, which was coordinatively grafted onto the surface of the UiO-67 nanoparticles. Then, PLMA brushes were grown on the macroinitiator-modified UiO-67 by surface-initiated atom transfer radical polymerization, which greatly improved the lipophilic property of the UiO-67 nanoparticles and significantly enhanced the colloidal stability and long-term dispersity in both non-polar solvent and base oil. By adding UiO-67@PLMA nanoparticles into the 500 SN base oil, coefficient of friction and wear volume reductions of 45.3% and 75.5% were achieved due to their excellent mechanical properties and oil dispersibility. Moreover, the load-carrying capacity of 500 SN was greatly increased from 100 to 500 N by the UiO-67@PLMA additives, and their excellent tribological performance was demonstrated even at a high friction frequency of 65 Hz and high temperature of 120 °C. Our work highlights oil-soluble polymer brushes-functionalized nanoMOFs for highly efficient lubricating additives.

Friction-reducing and anti-wear performance of SiO2-Coated TiN nanoparticles in gear oil

This article proposes modification of TiN nanoparticles via the sol-gel method and grafting reaction to prepare TiN@SiO2 nanocomposites (TiN@SiO2-RC), which was added into 85W90 gear oil as lubricant additive. The microstructure and oil dispersion stability of these nanocomposites were analyzed using transmission electron microscopy, potentiometer, infrared spectroscopy, and X-ray diffraction. Additionally, the tribological performance of these oils was evaluated using a four-ball friction and wear test machine. The 2D and 3D morphology, elemental composition, and chemical states of the worn surface on friction pair were comprehensively analyzed using scanning electron microscopy, 3D confocal microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy.Results show that the modified TiN nanoparticles exhibit considerably better dispersivity and stability than original TiN nanoparticles in 85W90 gear lubricating oil. At a mass concentration of 0.4 wt%, the 85W90 gear oil containing TiN@SiO2-RC achieved a substantial reduction of up to 14.6 % in the friction coefficient and a remarkable decrease of up to 23.2 % in the wear scar diameter. Notably, the nano-additives on the friction surface underwent chemical reactions to form reactive films, while the nonreactive nanoparticles mainly contributed to the formation of physical deposition films and acted as rolling bearing, improving the overall friction-reducing and antiwear properties.

Synergistic lubrication mechanism of nanodiamonds with organic friction modifier

Nanoparticles and organic friction modifiers (OFMs) as lubricant additives have shown great potential in friction and wear reduction by forming tribofilms which prevent direct contact at the sliding interface. Potential mechanisms for the formation of these tribofilms remain poorly understood, limiting the ability to optimise the performance of the entire tribosystem. Incorporation of nanoparticles and OFM together in a lubricant could provide a unique solution to enhance frictional and wear properties. In this study, Nanodiamonds (NDs) and Glycerol Monooleate (GMO) have been added to a PAO base oil containing low concentration of Zinc dialkyl dithio-phosphate (ZDDP) to produce a novel lubricant combination that significantly reduces coefficient of friction (COF) and wear. Experimental studies showed that NDs reacted with additives present in the lubricant combination to expedite tribofilm formation. Friction reduction performance can be attributed to the encapsulation of carboxylated NDs due to tribochemical interaction with GMO, their mechanical interlocking in the tribofilm and polishing effect of NDs. The visible presence of NDs in tribofilms and the formation of a thicker tribofilm layer with NDs have been corroborated for the first time in this study. Synergy achieved among NDs, GMO, and low concentration ZDDP to formulate a novel environmentally friendly lubricant with advanced tribological performance has been shown, providing a great potential to develop sustainable tribological solutions for a wide variety of engineering applications.

Transforming water-soluble carbon dots with high particle size regularity as the high-performance oil-based lubricant additives by one-step surface modification

Developing high-performance carbon dot (CD)-based lubricant additives towards non-polar base oils is always challenging because it is an arduous task to gain hydrophobic CDs with high quality. In this work, with the aid of the chemical reaction between hydroxyl groups and lauroyl chloride molecules, the water-soluble CDs-OH derived from the solvothermal method with particularly high particle size regularity were transformed as the oil-soluble CDs-LA by the one-step surface modification process. As expected, the CDs-LA capped by abundant long alkyl chain groups exhibited excellent long-term dispersion stability in non-polar base oil of polyalphaolefin (PAO4) and hence could be served as the additives of PAO4 directly. Under the same test conditions, the tribological performance of CDs-LA was obviously superior to the hydrophobic CDs obtained by the pyrolysis method, implying that the high particle size regularity was beneficial for making full use of the lubrication functions of CDs. Loading 1.7 wt% of CDs-LA made the friction and wear of PAO4 reduced by 32.2 % and 76.4 %, respectively. When the duration prolonged from 20 min to 200 min, the friction reduction of base oil triggered by CDs-LA further enlarged to 46.9 %. The friction-reducing and anti-wear performance of CDs-LA under high loads was also satisfactory. The worn surface analysis results demonstrated that the robust and homogenous boundary lubrication films composed of FexOy and CDs have generated on the rubbing surfaces lubricated by CDs-LA/PAO4 dispersion, well accounting for the outstanding friction reduction and wear resistance functions of CDs-LA.

Tribological behaviors of nano-schistose MSH in phosphate/graphite composite lubricating coatings under different friction temperatures

Nano-schistose MSH was incorporated to enhance the tribological properties of phosphate/graphite composite coatings at various friction temperatures. The composite coatings demonstrated optimum friction-reducing and anti-wear performance at 200 ℃ due to synergistic friction between nano-schistose MSH and graphite. However, the friction-reducing performance of the composite coatings declined at 500 ℃ due to the structural cleavage of nano-schistose MSH. Nevertheless, a composite tribo-film with exceptional mechanical properties was in-situ formed on the worn surface through tribo-chemical and mechano-chemical reactions between nano-schistose MSH and the counterface. Consequently, further abrasion on the worn surface was effectively reduced during the friction process, resulting in a significantly prolonged service life of the composite coatings even at 500 ℃.

Size-Regulated Metal-Organic Frameworks with Mercaptobenzothiazole for Ga-Based Liquid Metal Encapsulation: A High Performance Oil-Based Additive.

In this study, size-regulated MOFs (MZ) with high MBT loading were successfully synthesized by combining mercaptobenzothiazole (MBT), zinc salt, and 2-methylimidazole (2-MI). Subsequently, the MZ structure was utilized to encapsulate tannic acid-modified gallium-based liquid metal (GLM-TA), thereby acquiring a novel heterogeneous nanocomposite (GLM-TA@MZ). The results revealed that the as-prepared GLM-TA@MZ shows good antiwear and friction-reducing performance as an oil-based lubricant additive, the average friction coefficient was decreased to 0.091, and a wear volume was reduced to 0.95 × 104 μm3, which corresponds to a decrease of 52.3 and 97.2% as compared to base oil PAO. The excellent tribological properties of GLM-TA@MZ can be attributed to physical adsorption on the friction pair, followed by tribochemical reactions. As a result, a thick friction protection film (thickness of about 100 nm) containing Ga, Zn, and S elements was formed, which effectively reduced the contact area between the friction pairs, resulting in improved tribological performance. This study provides insights into the design of MOF-based nanocomposites for lubricating applications.

Synergistic effect of sodium dodecyl sulfate (SDS) and oleic acid (OA) on gelation and lubrication performance

In this paper, it was found that with the addition of sodium dodecyl sulfate (SDS, a hydrophilic surfactant) and oleic acid (OA, a lipophilic surfactant) in a solvent with a proper composition ratio, a stable gel could be obtained via a simple ultrasonic treatment. The synergistic gelation of OA–SDS was verified in a series of solvents with different polarities, such as white oil (WO), LB-2000, n-hexane, polyalphaolefin (PAO10), and deionized water. The Fourier transform infrared (FTIR) analysis confirms that the gelation of OA–SDS is highly related to the ion exchange reaction between them. However, the xerogel of OA–SDS gelator in deionized water and WO (OSW) exhibited remarkably different morphologies, indicating that the gelation is based on different molecular assembly processes, which is governed by the orientation of the two surfactant molecules in liquid media. Further characterizations of OSW gel presented that the synergistic effect between OA and SDS not only existed in gelation, but also in enhancing the mechanical and thermal stability of WO, and endowing the OSW gel with reliable friction reduction and antiwear performances under variable working conditions. Subsequently, the lubrication mechanism was proposed based on rheological analysis and the morphological and compositional analysis of wear surfaces. This study provides a novel idea for the molecular design of lubricating gelators with wide adaptability to solvent polarity and working conditions.

Fretting wear behavior of oxide dispersion strengthened nanocrystalline-amorphous FeCr film

Fretting wear is potential safety hazard for critical structural components in various industries, including nuclear reactors and aerospace. Surface treatment can effectively reduce damage caused by contact. The focus of this work is to prepare Y2O3 oxide dispersion strengthened FeCr-based films by magnetron sputtering. The distribution of Y2O3 and its effects on the mechanical properties, as well as the fretting wear behavior of the films were characterized in detailed. The results show that Y2O3 nanoparticles are uniformly dispersed in the FeCr films matrix, forming a nanocrystalline-amorphous composite structure. As the Y2O3 content increases, the FeCr films show a trend of grain refinement and hardness increase. The fretting wear tests of FeCr-based films sliding against Al2O3 and GCr15 counterparts were conducted, and the best friction-reducing performance was achieved when the co-deposition power of Y2O3 is 70 W. To elucidate the underlying friction mechanism, transmission electron microscopy (TEM) characterization was utilized to reveal the microstructure evolution of the films and the contribution of friction products. This study provides valuable insights into the development of wear-resistant materials made from nanocrystalline-amorphous dual-phase structure films dispersed by rare earth oxides.
