“…Creating sustainable coatings for metal alloys is now a difficulty. Regarding surface modification, many research works have been pursued to enhance the tribological behaviour of Al 6061-T6 alloy using sputtering, anodizing [3], processing of laser [4], plasma and thermal spray [5] as stated in the research. The surface mentioned above modification techniques required specialized methods with post-treatments.…”

This research investigates the tribological characteristics and sustainability of WS 2 deposited Al 6061-T6 surface under dry sliding conditions and optimizes the wear parameters to enhance the tribological behaviour and discuss its sustainability. The experiment used the Box-Behnken design, which examines the effective interaction between dry sliding parameters and specific wear rate (SWR) and friction coefficient (COF). By varying the load (L), sliding velocity (V) and distance (D), the wear behaviour of WS 2 deposition against EN 31 steel was examined through the pin-on-disc experiment. Grooving, debris formation, polishing, tribolayer, ploughing, transfer material, smearing, delamination and pitting are observed through scanning electron microscope (SEM) analysis. For optimum conditions, SEM with energy dispersive spectroscopy was utilized to characterize the worn surface, and X-Ray diffraction (XRD) patterns confirmed the phases of W, WO

“…The advanced surface modification process is a tool to improve friction and abrasive wear resistance. Many researchers have attempted to improve the surface properties of Al 6061-T6 alloy through laser processing (Chi et al , 2021), hard anodizing (Mohitfar et al , 2020), physical vapor deposition, laser shock processing and plasma spraying (Rajeshshyam et al , 2020) according to the literature. All of the treatments mentioned above need sophisticated equipment and post-curing processes.…”

Purpose This tribological investigation aims to identify the effect of WS2 deposition on the Al 6061 surface and optimize the dry sliding conditions to enhance the friction and abrasion wear behavior. Design/methodology/approach WS2-deposited Al 6061-T6 surface was considered for this tribological investigation. The design of the experiment was based on the Box–Behnken design of the response surface methodology approach, which is used to evaluate the interaction effect of input parameters on friction coefficient (COF) and specific wear rate (SWR). The abrasive wear behavior of WS2 deposition against SiC emery sheet was explored through pin-on-disc experimentation by varying applied load (L), sliding velocity (V) and distance (D). Using analysis of variance and regression model, COF and SWR were predicted. Findings Based on composite desirability criteria, multi-objective optimization was performed to minimize the COF and SWR. The obtained optimal sliding conditions are L = 10 N, V = 2 m/s and D = 949.49 m. The validation test results indicate that the experimental and predicted data are in good conformance. For optimized conditions, worn surface characterization was done using a scanning electron microscope with energy dispersive spectroscopy, and X-ray diffraction analysis was performed to ensure the formation of WS2 phases on worn-out surfaces. Furthermore, a counter body surface with collected wear debris has been analyzed. Originality/value Almost the industries are now focused on a new surface modification technique, which improves the surface and tribological characteristics. This research work specifically relates the tribological effect of WS2 deposition on an Al 6061-T6 surface through a novel electrical discharge deposition approach and optimizes the dry sliding conditions to improve the frictional and abrasive wear resistance.
