简介
Surface Texturing is the most significant technique to reduce friction in the frictional pairs. Tribological performance of the frictional pairs can be improved by controlling the geometrical shape, dimple diameter to depth ratio and area density ratio. In this study, tribological performance of the brass discs with various surface textures mated with brass pins were experimentally analyzed using pin on disc tribometer. Laser marking machine was used to produce surface textures like Circular arrays of spherical and ellipsoidal dimple features with various aspects and area density ratio. The dimple shape and size are experimentally analyzed under dry lubrication. The influence of three kinds of dimple textures on friction characteristics was studied. It shows that there is a positive effect on dimpled surfaces compared to smooth surfaces. Controlling the dimple size and shape plays an important role in surface texturing.
