Investigating the Effect of Surface Texture on Friction and Wear in Sliding Contacts

Numerous industrial applications have shown that altering the surface geometry enhances the tribological performance of lubricated sliding contacts.The purpose of the current study is to look at how surface roughness affects wear and friction in sliding contacts. The performance and durability of many engineering systems, including mechanical parts, bearings, and automotive applications, are significantly influenced by friction and wear. Understanding how surface texture affects these tribological processes can help us improve efficiency and lower energy losses in these systems. In this paper discussed the surface roughness has a big impact on how friction and wear behave in sliding contacts. When compared to smoother surfaces, it was found that some texture patterns, such as micro-grooves and dimples, have lower friction coefficients and wear rates. This is due to the smaller contact area, enhanced lubrication, and increased oil retention capacity offered by the surface roughness. The directionality of the textures also significantly affected how well they performed tribologically, with some orientations performing better than others.The study found that the ideal surface roughness for reducing friction and wear depends on the particular operating circumstances. When choosing a suitable texture pattern, factors including load, sliding speed, and lubricant type must be taken into account
