A Recent Trend In Surface Modification: An Introduction

To improve the original surface properties always require modification so that enhanced surface property is obtained. So many techniques are available for improving the surface properties of the original substrate, which comes under the area of the coating. Some of them are ion implantation, laser alloying, dipping, diffusion, and melting method, electrolysis based and mechanical methods. In recent years surface modification through non-traditional machine i.e. EDM is also possible. EDM is a very well-known advanced machining process. Since in the process of machining by EDM there is always wear of tool is noticed which leads to the further invention of material transfer on the workpiece. This new method is known as an electric discharge coating. This paper describes the introduction of the electric discharge coating process and its recent research.
