ABSTRACT

Surface treatment is an important aspect of all manufacturing processes. Surfaces and their properties are as important as the bulk properties. Therefore, the surface produced should be free of cracks and residual stresses. Furthermore, it should not be subjected to undesirable metallurgical changes [1]. Surface treatment has been used to impart certain physical and mechanical properties, such as appearance, corrosion, friction, wear, and fatigue resistance. Several techniques are available for modifying surfaces, including mechanical working (such as grinding, honing, lapping, etc.), coating, heat treatment, deposition, and plating [2]. Widely used methods of finishing treatment usually do not provide the optimum quality of the surface. However, green surface plastic deformation (SPD) methods such as diamond pressing (DP), roller burnishing (RB), and shot peening (SP) are used.
