Abstract: Surface engineering allows for the alteration of the properties of the substrate material to meet a demand that is distinct from the bulk material. Titanium and its alloys are reported to have weak tribological qualities that must be improved by a variety of methods. In this study, a single layer of TiAlN was deposited on the Ti-6Al-4V ELI substrate using the Physical Vapor Deposition (PVD) method. The study's goal is to analyze and optimize the sliding wear behavior of coated and uncoated samples. To examine input factors on response parameters, Response Surface Methodology (RSM) was adopted. The input factors for the experimental works were Load, Sliding speed, and Sliding Distance, while the response parameters were Wear Mass Loss (WML) and Coefficient of Friction (CoF). The WML and CoF of the coating material were evaluated under dry sliding conditions at ambient temperature and humidity. WML was calculated using the difference in weight before and after the experiment. The CoF was automatically recorded by the tribometer data collection system. To investigate and identify factors that influence the answer value, the ANOVA approach was utilized. To attain the lowest WML and CoF, a desirability-based optimization strategy was used. The best parameters for uncoated samples were 30 N, 1.31 m/s, and 1000 m, and 30 N, 1.0 m/s, and 1000 m for coated samples. Micro structural pictures of worn-out samples were used to examine the wear tracks. Because of the similarity in elemental makeup between the coating and the substrate material, the appearance of visible scratches, grooves, confirms abrasive wear as the main wear mechanism, accompanied by adhesive wear. It was discovered that coated samples had a 25.42 percent improvement in WML when compared to untreated ones. According to the findings, TiAlN offers superior wear resistance capabilities.
