In recent years, the valve train of automobile engine has been actively developed to obtain superior intake and exhaust efficency and thermal efficency at same time. Therefore, the working conditions of cameshafts have become more severe. There is increasing demand for camshaft materials which have higher wear resistance. Remelting process only at the friction area of cam face with highly cocentrated prasma arc energy and adding alloying elements to the melt pool will create a new alloying layer with high wear resistance. This paper describes the development of plasma surface modification technique, the feature of this process and the characteristics of the alloyed layer etc.
