A Study on Improvement of Fatigue Life of materials by Surface Coatings

Abstract

Fatigue failure is one of the main reasons for the mechanical failure in engineering materials. To improve the fatigue strength of the material one of the most used method is surface treatment of the materials in which hardness, wear resistance and aesthetics is improved. In this paper the different methods of surface coatings, types of fractures that occur in the material during fatigue testing and effect of the fatigue life on the material is studied
