The effect of surface texturing in the sliding surface on tribological characteristics of alloy steel under wet condition

Surface texturing plays a significant role on the tribological performance of contact surfaces. The tribological characteristics are mostly dependent upon the different pattern and methods of surface texturing. This research works investigates lubricated wear behaviour on circular dimples textured...
