Abstract
Abstract Surface modifications have been applied to metal in order to improve the mechanical, chemical and physical properties, such as wear and hardness. Surface modification is found on the part surface of the automobile parts like turbochargers. Surface modification of stainless-steel alloy by plasma treatment is achieved using different gases such as air, nitrogen, argon and helium. The objective of plasma surface modification is to enhance the surface wettability, reduce surface friction, to reduce the wear rate and to avoid surface crack propagation on the components, to improve of surface properties against wear and other factors. In this project SS310 material is selected as the base material which is used for turbocharger. This SS310 material is machined and undergone plasma nitriding at a temperature of 450 °C for 4 h. The plasma nitrided specimens have undergone different tests such as roughness, wear and hardness From all the test results, it is concluded that the material undergone heat treated plasma nitriding exhibits better mechanical and tribological properties such as roughness, hardness and wear resistance for the automobile components. This brings better service life of mating components in a successful way.
