Role B4C Addition on Microstructure, Mechanical, and Wear Characteristics of Al-20%Mg2Si Hybrid Metal Matrix Composite

In the current study, the effect of different B4C additions (0, 2.5, 5, and 10 wt%) on the microstructural, solidification behavior, mechanical, and tribological properties of Al-20%Mg2Si composite were studied by means of scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Vickers hardness, tensile, and dry sliding wear tests. The cooling curve thermal analysis (CCTA) approach was utilized to monitor the influence of B4C particles on the solidification behavior of Al-20%Mg2Si composite. The results revealed that the addition of B4C particles up to 10 wt% reduced the nucleation temperature (TN) and growth temperature (TG) of the primary Mg2Si phase. Moreover, the proper amount of B4C added to Al-20%Mg2Si composite has a significant effect on the microstructural alteration, mechanical, and tribological properties of the composite. The mean size of primary Mg2Si in Al-Mg2Si composite was 47 μm, in which with the addition of 5 wt% B4C, the particle size decreased to 33 μm. The highest UTS (217 MPa) and El% (7%) was achieved in Al-20%Mg2Si-5%B4C hybrid composite. The cast Al-20%Mg2Si composite revealed the brittle mode of fracture with some cleavage characterization, in which with the addition of 5%B4C, the fracture mode altered to a more ductile fracture. The wear results revealed that the Al-20%Mg2Si-5%B4C hybrid composite has the highest wear resistance with the lowest wear rate (0.46 mm3/Km) and friction coefficient (µ = 0.52) under 20 N applied load compared to other fabricated composites with mild abrasion as the governed wear mechanism.

Influence of post-treatment process on corrosion and wear properties of PEO coatings on AM50 Mg alloy

In the present work, post-treatment process has been applied to improve the corrosion and wear resistance of plasma electrolytic oxidation (PEO) coated AM50 Mg alloy. The microstructure, chemical composition and corrosion resistance of the PEO/organic composite coatings were studied by means of SEM, FTIR, electrochemical corrosion test and salt spray test. The wear resistance of the coatings was investigated by performing dry sliding wear test. The results showed that sol-gel and epoxy layer were efficient to seal the open pores and therefore greatly enhanced the corrosion performance of PEO coatings, while hybrid coatings sealed by epoxy layer showed better corrosion and wear resistance. It was found that relatively long dipping time applied during post-treatment process is capable of fabricating denser coatings with superior coating properties. The open pores of the PEO coating are penetrated and filled effectively after performing post-treatment process, resulting in high adhesion force for the composite coatings.

Comparison of dry sliding tribological behavior of SS 316L impregnated with MoS2 vs h-BN solid lubricants: A statistical point of view

The main aim of this paper is to statistically discuss the friction and wear behavior of 316L stainless steel (SS316L) composites added with h-BN and MoS2 solid lubricant under different running conditions at room temperature. The SS316L composites added with h-BN and MoS2 were produced by the powder metallurgy method. The mixture of SS316L composites with 15 and 20 vol% of h-BN and MoS2 were cold compacted into ∅ 30 mm cylinder parts. Then sintered in the sintering furnace under H2 atmosphere for 60 min. Brinell's hardness and dry-sliding wear behavior of the sintered SS316L composites were investigated using a pin-on-disc testing machine. The factorial experimental design was employed to investigate the influence of specific independent variables on dry sliding wear, testing at sliding speeds of 0.1 and 0.2 m/s, applied load of 3 and 5 N and sliding distance varying from 100 to 200 m. The effects of tested variables on the specific wear rate and coefficient of friction were analyzed from both statistic plots and physical analyses of worn surface with SEM micrographs. The results showed that the MoS2 added composite resulted in greater wear resistance than h-BN added composite. The wear resistance and friction coefficient on dry sliding wear test also depended on the interaction effect of sliding distance, sliding speed and applied load which are relative to the formation of tribofilm on sliding interfaces. In addition, sliding speed influence to the formation of tribofilm showed significantly high levels of wear resistance and friction coefficient of composites. The statistical design of this experiment enabled us to collect and analyze wear data which provided a greater understanding of the complex mode/mechanism of sliding wear of SS316L self-lubricating composites.

Microstructure, Hardness, Tensile Strength, and Sliding Wear of Hypoeutectic Al–Si Cast Alloys with Small Cr Additions and Fe‐Impurity Content

Herein, the influence of Cr additions on the solidification parameters, as‐cast microstructures, and mechanical properties of Al–Si alloys with Fe‐impurity is investigated. Al–Si–Cr alloys with 3% and 7% Si and 0.25% and 0.40% Cr are developed. Solidification experiments are performed using an instrumented cooling casting apparatus permitting the obtainment of vertical upward‐solidified ingots. The morphological and phase structures are characterized by optical and scanning electron microscopy and X‐ray diffractometry. Hardness, tensile, and dry sliding wear tests are conducted to determine the mechanical properties. The Cr addition to the Al–Si alloys leads to the formation of α‐Al(Si, Fe)Cr interdendritic precipitates, suppressing the formation of undesired needle‐like β‐intermetallic compounds (Al5FeSi). It is noted that both higher alloy Cr content and cooling rate induce refinement in the dendrite arm spacing, and improvement in both hardness and ultimate tensile strength when considering the alloys with identical Si content. The coefficient of friction slightly increases with increasing alloy Cr content and with coarsening of the microstructure. Correlations between the wear rate and secondary dendrite arm spacing are proposed, in which the wear rate decreases with decrease in the secondary dendrite arm spacing and increase in the alloy Cr content and hardness.

Hot Sliding Wear of 88 wt.% TiB-Ti Composite from SHS Produced Powders.

Titanium alloys and composites are of great interest for a wide variety of industrial applications; however, most of them suffer from poor tribological performance, especially at elevated temperatures. In this study, spark plasma sintering was utilized to produce a fully dense and thermodynamically stable TiB–Ti composite with a high content of ceramic phase (88 wt.%) from self-propagating high temperature synthesized (SHS) powders of commercially available Ti and B. Microstructural examination, thermodynamic assessments, and XRD analysis revealed the in situ formation of titanium borides with a relatively broad grain size distribution and elongated shapes of different aspect ratio. The composite exhibits a considerable hardness of 1550 HV30 combined with a good indentation fracture toughness of 8.2 MPa·m1/2. Dry sliding wear tests were performed at room and elevated temperature (800 °C) under 5 and 20 N sliding loads with the sliding speed of 0.1 m·s−1 and the sliding distance of 1000 m. A considerable decline in the coefficient of friction and wear rate was demonstrated at elevated temperature sliding. Apart from the protective nature of generated tribo-oxide layer, the development of lubricious boric acid on the surface of the composite was wholly responsible for this phenomenon. A high load bearing capacity of tribo-layer was demonstrated at 800 °C test.

Effect of silica nanoparticles on physical, mechanical, and wear properties of natural fiber reinforced polymer composites

AbstractHemp‐sisal natural fiber‐reinforced hybrid epoxy composites containing a varying proportion of silica nanoparticles (0, 1, 2, 3, and 4 wt%) were manufactured and subsequently evaluated for physical, mechanical, and sliding wear properties. The density of the composite was found to increase, whereas void content was found to decrease with the increase of silica nanoparticles content. The composites containing 2 wt% silica nanoparticles exhibit maximum tensile strength, impact strength, and hardness, whereas the composite with 3 wt% silica nanoparticles showed the highest flexural strength. Dry sliding wear tests of the manufactured composites were carried out on a pin‐on‐disc machine under different sliding speeds, distances and applied loads at room temperature. Taguchi based L16 orthogonal array design was used to find the optimum combination of control factors resulting in higher wear resistance. The analysis reveals that the silica nanoparticles contribute the most towards wear performance with a contribution ratio of 32.61% and a combination of 2 wt% of silica nanoparticles, 10 N normal load, 1.5 m/s sliding speed and 500 m sliding distance resulted in higher wear resistance.

Study on mechanical and wear properties of hypereutectic Al-18Si-3.6Cu-0.34Ce alloy

In the present study an effort was made to find the mechanical and wear properties of a heat treatable hyper eutectic aluminium-silicon alloy. The alloy was prepared by conventional casting method in the form of ingots, and then chemical compositions of the alloy analysis are made by spectro spark emission spectrometer. The as cast alloy test samples are T6 heat treated by solutionizing at 500°C for 1h followed by water quenching and isothermal ageing treatment at 210°C for different aging time was achieved. The tensile test was carried out for as cast and cast aged conditions of different aging time of 1h, 3h, 5h and 7h. It was observed from tensile test the ultimate tensile strength of 1h (193.83Mpa) and 3h (168.68Mpa) aged (T6 treated) samples improved the UTS by 22% and 7% respectively as compared to as cast sample (158Mpa). Dry sliding Wear test was conducted at constant sliding speed of 1m/s, 2m/s, 3m/s and 4m/s. with varying load 10-40N. From the dry sliding wear study confirmed that wear rate and coefficient of friction are load dominant, In spite at higher sliding speed and load lower friction was noticed.

Novel utilization of powder-suspension hybrid feedstock in HVAF spraying to deposit improved wear and corrosion resistant coatings

Deployment of a suspension feedstock has been known to alleviate problems associated with using sub-micron and nanosized powder feedstock for thermal spraying of monolithic as well as powder-suspension ‘hybrid’ composite coatings. However, a powder-suspension hybrid feedstock has never been previously used in high-velocity air-fuel (HVAF) spraying. In this work, for the very first time, a chromium carbide (Cr3C2) suspension has been co-sprayed along with an Inconel-625 (IN-625) powder by the HVAF process as an illustrative case study. Two variants of the IN-625 + Cr3C2 hybrid coatings were produced by varying relative powder-suspension feed rates. For comparison, pure IN-625 coating was also deposited utilizing identical spray parameters. Detailed microstructural characterization, porosity content, hardness measurement and phase analysis of the as-deposited coatings was performed. The suspension-derived carbides were retained in the bulk of the coating, resulting in higher hardness. In the dry sliding wear test, the hybrid coatings demonstrated lower wear rate and higher coefficient of friction (CoF) compared to the conventional, powder-derived IN-625 coatings. Furthermore, the wear rate improved slightly with an increase in Cr3C2 content in the hybrid coating. Post-wear analysis of the worn coating, worn alumina ball and the wear debris was performed to understand the wear mechanisms and material transfer in the investigated coatings. In the potentiodynamic polarization test, higher corrosion resistance for hybrid coatings than conventional IN-625 coatings was achieved, indicating that the incorporation of a secondary, carbide phase in the IN-625 matrix did not compromise its corrosion performance. This work demonstrates a novel approach to incorporate any finely distributed second phase in HVAF sprayed coatings to enhance their performance when exposed to harsh environments.

Development of Fe-5Al-1C alloys for grinding ball

Our object of research is to combine the properties of Mn and the advantages of Fe-Al-C to improve the performance of grinding ball materials. Three Fe-5Al-1C alloys with compositions of 15 wt% Mn (FAM15), 20 wt% Mn (FAM20), and 25 wt% Mn (FAM25) were investigated. Argon gas was used to assist the removal of dissolved oxygen and to control the formation of metal oxides during Fe-Al-Mn-C (FAMC) fabrication. Microstructure analysis was conducted using scanning electron microscopy, and the Vickers microhardness tester was used to evaluate hardness. To guarantee the Fe-5Al-1C-Mn alloy phase, X-ray diffraction (XRD) test was performed. The EDS test was carried out to show the composition at different points and to observe the presence of several phases in the FAMC alloy system. A pin-on-disc method was employed for a dry sliding wear test, and corrosion testing was performed using the three-electrode cell polarization method. With the addition of Mn, the Vickers hardness of the FAMC alloy raised from 194.4 VHN at 15 wt% to 265 VHN at 25 wt%. The tensile strength and fracture elongation values were 424.69 MPa, 27.16 % EI; 434.72 MPa, 33.6 % EI; and 485.71 MPa, 38.48 % EI for FAM15, FAM20, and FAM25, respectively. A crucial factor for increasing the performance of grinding ball is the wear mechanism. The wear rate results for FAM25 show a decline of more than 57 % compared to FAM15 due to an increase in the hard intermetallic area. The addition of Mn elements increased the corrosion resistance of the FAMC alloys; the lowest corrosion rate occurred at 25 wt% Mn content at up to 0.036 mm/yr. According to the experimental results, the FAM25 alloys have the highest mechanical and corrosion resistance of the three types of alloys. The FAMC alloy is a promising candidate for application as a material for grinding balls by optimizing the Mn content

Achieving low wear in a μ-phase reinforced high-entropy alloy and associated subsurface microstructure evolution

Face-centered cubic (fcc) high-entropy alloys (HEAs) with dispersed hard intermetallic compounds have demonstrated a good combination of high strength-ductility. However, limited research effort has been devoted to exploring their siding wear behavior. Herein, we report the effects of load and sliding velocity on the dry sliding wear behavior Fe40Co20Mo20Ni20 HEA consisting of an ultrafine-grained (UFG) fcc matrix and a high density of dispersed hard μ-phase. Pin-on-disk dry sliding wear tests show that the Fe40Co20Mo20Ni20 HEA exhibits low wear rates of the order of 10−6–10−5 mm3/(N·m) at different test conditions. The wear rates and coefficients of friction generally increase with load and sliding velocity, but wear modes show no apparent change, all in the form of abrasive, oxidation and fatigue wear. Sliding-induced gradient microstructure was formed, consisting of a nanostructured glaze layer at the sliding surface and two typical plastically deformed regions further away from the surface. The presence of massive hard μ-phase particles is suggested to hinder the plastic flow of the fcc matrix during sliding, thereby achieving low wear.

Effect of Variation of SiC Reinforcement on Wear Behaviour of AZ91 Alloy Composites.

In this investigation, the extensive wear behaviour of materials was studied using SiC reinforced magnesium alloy composites fabricated through the stir casting process. The wear properties of AZ91 alloy composites with a small variation (i.e., 3%, 6%, 9% and 12%) of SiC particulates were evaluated by varying the normal load with sliding velocity and sliding distance. The worn surfaces were examined by scanning electron microscope to predict the different wear mechanisms on the pin while sliding on the hard disk in the dry sliding wear test condition. The microhardness of the SiC reinforced AZ91 composites was found to be more than the un-reinforced AZ91 alloy. Pins tested at load 19.62 N, and 2.6 m/s exhibited a series of short cracks nearly perpendicular to the sliding direction. At higher speed and load, the oxidation and delamination were observed to be fully converted into adhesion wear. Abrasion, oxidation, and delamination wear mechanisms were generally dominant in lower sliding velocity and lower load region, while adhesion and thermal softening/melting were dominant in higher sliding velocity and loads. The wear rate and coefficient of friction of the SiC reinforced composites were lower than that of the unreinforced alloy. This is due to the fact of higher hardness exhibited by the composites. The wear behaviour at the velocity of 1.39 m/s was dominated by oxidation and delamination wear, whereas at the velocity of 2.6 m/s the wear behaviour was dominated by abrasion and adhesion wear. It was also found that the plastic deformation and smearing occurred at higher load and sliding velocity.

Exploitation and Wear Properties of Nanostructured WC-Co Tool Modified with Plasma-Assisted Chemical Vapor Deposition TiBN Coating

In recent years, coated cemented carbides have often been the first choice for a wide variety of tool inserts and applications. Its success as a cutting tool material arises from the unique combination of wear resistance and toughness, and its ability to be formed into complex shapes. The structure obtained by sintering nanoparticle powders provides a significant improvement in product properties, such as higher cutting speeds, lower tool tolerances, and longer service life. In this study, a multi-layered gradient coating, deposited on nanostructured cemented carbides by plasma-assisted chemical vapor deposition (PACVD) was investigated with emphasis on its wear and exploitation properties. TiBN coating was deposited on nanostructured cemented carbide samples with the addition of 5 wt% Co, 10 wt% Co and 15 wt% Co. The samples were consolidated by one cycle hot isostatic pressing (HIP) technique. Complex architecture built of TiN and TiB2 gradient multilayer sequence block was deposited on each type of substrate. Wear resistance of the obtained samples was determined by erosion wear testing and dry sliding wear testing (ball-on-flat test). The friction coefficients of ~0.22 obtained for coated samples by the ball-on-flat test show a decrease in friction when compared to uncoated samples values of ~0.32. The absence of coating rupture was confirmed by wear track depth measurements showing a wear trace depth of ~1.2 μm. Exploitation properties i.e., tool life determination of samples was obtained using single-point turning tool test and compared to commercial cutting tool insert type K10 tested under the same conditions. All the conducted tests show excellent wear and exploitation properties of the newly developed TiBN coating under chosen conditions, including cutting speed, vc = 200 m/min, depth of cut, ap = 1 mm, and feed, fn = 0.2 mm. Coated WC-Co samples with 15 wt% Co, having withstood 15 min of machining with flank wear trace size less than 0.3 mm, suggest significant improvement when compared to trace size of 0.56 mm obtained for K10 commercial cutting insert.

Sliding wear performance of in-situ spark plasma sintered Ti-TiBw composite at temperatures up to 900 °C

Although Ti-based composites find wide industrial applications, their tribological behaviour, especially at elevated and high temperatures, is not conclusively evaluated. In this work, a sliding wear performance of metal – ceramic composite of 50 wt%Ti–50 wt%TiBw, which were in-situ produced by spark plasma sintering, was studied. Microstructural examination and X-ray diffraction analysis identified presence of two phases, Ti and TiB, and confirmed the formation of stable TiB whiskers-like grains (TiBw) during reaction synthesis of Ti and TiB2. Ball-on-plate dry sliding wear tests were performed against a 10 mm alumina ball under 5 N normal load with the sliding speed and distance of 0.1 ms−1 and 1000 m, respectively. The tests were performed at RT and elevated temperatures of 300 °C, 500 °C, 700 °C, 800 °C and 900 °C. The worn surfaces were studied using scanning electron microscopy and 3D profilometry to understand the responsible wear mechanisms. Results have demonstrated significantly reduced wear rates of Ti-TiBw composite as compared to reference pure Ti across all temperatures. The formation and the protective role of tribo-oxide layers on the surface of Ti-TiBw composite during elevated temperature sliding is reported.

Assessment on the impact of FSP process parameters on microstructural, mechanical and wear behaviour of FSPed AA6082

The present research work demonstrates the effect of friction stir process (FSP) and its process parameters (rotation speed and travel speed) on the microstructure evaluation, microhardness and wear behaviour of FSPed AA6082. The microstructure characterization of the processed samples was examined using the Optical Microscope (OM). Dry sliding wear test was carried out by varying the sliding velocity (0.5, 0.75 and 1.0 m s−1) and applied load (5, 10 and 15N) using the pin on disc apparatus. Wear mechanisms experienced by the FSPed AA6082 were mapped, and the optimal FSP and wear parameters have been determined using Taguchi analysis. The results showed that there is a significant improvement in the microhardness (92 HV 0.3) and wear resistance for RS 1250 rpm & TS 40 mm min−1 due to the grain strengthening mechanism and microstructure modification. Formation of oxide layer played a crucial role on the wear resistance of the FSPed AA6082 and its significance has been discussed elaborately using the Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS).

Wear behaviours of PVD-TiN coating onTi-6Al-4V alloy processed by laser powder bed fusion or conventionally processed

Ti-6Al-4V alloy is the most preferred alloy used in laser powder bed fusion (LPBF) and physical vapour deposition (PVD) coating may often be needed. However, whether the wear performance of the coating on the high hardness LPBF Ti-6Al-4V substrate may perform differently to that on the conventionally processed (CP) and significantly lower hardness alloy substrate has not been clear. In this study, dry sliding wear tests have been conducted on PVD TiN-coated Ti-6Al-4V samples processed either by LPBF or by CP, using WC-Co as counter material. It has been found that local fracturing of coating after being thinned to 0.4–0.5μm in both coated LPBF and CP samples is similar. The major wear mechanism leading to a gradually rapid increase in wear rate of the coated samples will be demonstrated and explained through a wear process described as thickness reduction and local fracturing of the coating before the widening of the wear track. It will be shown that the local fracturing of coating was accompanied by the local deformation in CP substrate due to its low hardness. For the LBPF substrate, the deformation was not readily observed. That the higher amount of deformation underneath the coating for the case of CP substrate has affected little the overall wear rate will be illustrated.

Influence of the dendritic microstructure and β-Al5FeSi phase on the wear characteristics in a horizontally solidified Al-7Si-0.4Mg-1.2Fe alloy

In this work an Al-7Si-0.4Mg-1.2Fe alloy (wt.%) was subjected to a horizontal solidification experiment using a water-cooled solidification device equipped with thermocouples to obtain temperature vs. time data which in turn allowed solidification thermal parameters, such as growth and cooling rates (VL and TR, respectively), to be determined. In turn, tribological behavior of samples with different secondary dendritic spacing (λ2) and β-Al5FeSi platelets length (βFe) were assessed by means of dry sliding wear testing performed in a rotating fixed ball machine, with wear volume and rate (WV and WR, respectively) being the two main investigated wear parameters. Quantitative metallography by optical and scanning electron microscopy along with energy dispersive X-ray spectroscopy enabled both as-cast microstructures and worn craters to be characterized. More significant variations in wear resistance of the investigated alloy were found for ranges of λ2 and βFe that lie within 12−20 μm and 14–36 μm, respectively, with the coarsening of the microstructure constituted by Al-rich primary phase dendrites surrounded by α-Al + Si + θ-Mg2Si + β-Al5FeSi eutectic structures favoring reduced WV and WR values. For λ2 and βFe values higher than 24 and 48 μm, respectively, both WV and WR stabilize assuming constant values that depend on the sliding distance. In addition to power type equations relating λ2 and βFe to VL and TR, mathematical expressions for variations of WV and WR with λ2 and βFe are also proposed. Finally, a comparative analysis with the literature is presented.

Formation mechanism and function of tribo-layers in dry sliding wear of TC11 alloy

Dry sliding wear tests were performed for TC11 alloy through a pin-on-disc tribometer at a load of 50 N under different sliding velocities. Tribo-layers always formed on wear surfaces of titanium alloy at different sliding speeds. The formation of tribo-layers depended on the generation, movement, aggregation, transfer of wear debris and tribo-chemistry. Small wear debris and relatively high contact surface temperature were favorable conditions for formation of tribo-oxide layers. Tribo-oxide layers protected the titanium alloy matrix effectively and reduced the wear. The more oxides the tribo-oxide layer contained, the better it protected the matrix.

Effect of Stainless Steel Powder as Reinforcement on Mechanical and Tribological Properties of Stir Cast Zn-Al Alloy

In this study, Zn-40Al alloy is reinforced with 310 stainless steel particle of size 45 μm and its effect on tensile strength, hardness and wear rate were investigated. The Zn-40Al- SS composites were fabricated with 310 tainless steel particle of 3, 6, and 9 wt. % of volume fractions using stir casting technique. Tensile strength and vickers microhardness were tested for the base alloy and for the various combinations of Zn-40Al-SS composite. Dry sliding wear test using Pin-on-Disc machine were carried out for the base alloy and for all the combinations of the composites. Characterization techniques like optical microscopy, scanning electron microscope (SEM) and elemental distribution by energy-dispersive X-ray spectrometry (EDS) were carried out to analyse the composite. The tensile strength and hardness were high for the reinforcement of 9 wt. %. Also the wear resistance was maximum for the reinforcement of 9 wt. %. The microstructure shows the fine uniform dispersion of the reinforcing particles over the entire matrix. Overall the composite shows a significant improvement in the wear resistance and mechanical properties.

Effect of retrogression and re-aging on mechanical &wear properties of LM-25 aluminium alloy

.The effect of retrogression and re-aging on the mechanical and wear properties of LM 25 were studied. The raw material ingot was casted in to cylindrical rods. The samples were solutionized at 530 °C for 2 hours and then artificially aged at 165 °C for 12 hours. The samples were heat treated using retrogression process at temperatures 200 °C, 225 °C, 250 °C, and 275 °C and re-aged at 165 °C for 12 h. The samples were tested for its hardness and tensile strength and found that the 200°C retrogressed and re-aged sample (HT1) was having high hardness (125 HV) and the tensile strength was recorded as highest (182 N/mm2) when compared to other samples. Izod impact test was conducted for all the samples and it remains same for all the samples. Dry sliding wear test results shows that HT1 sample was having least wear rate when compared to other samples.Microstructure of HT1 sample reveals that the silicon precipitates of sleek and finer grain structure, which improves the hardness and tensile strength.

Dry sliding wear test on borided AISI 316L stainless steel under ball-on-flat configuration: A statistical analysis

In this paper, significant results about the evaluation of the influence of wear test factors such as load, distance, and sliding speed are analyzed to determine the statistical behavior of the specific wear rate, depth, and friction coefficient as response variables. Dry sliding wear tests were performed on the borided AISI 316L stainless steel under controlled environmental conditions, according to the ASTM G133-05 standard procedure, and a UMT-2 universal tester was used. The development of the analysis of variance showed that the load factor has the major statistical significance on the specific wear rate, depth, and CoF with 63.7%, 59.60%, and 62.67%, respectively. The response surface methodology was applied through the distance weighted least-squares fitting to explain the behavior of the response variables on the measured variables and the difference in the performance due to the total distance of sliding.
