Development of the wear- resistant composite material containing the diamond powder particle using underwater shock wave

Recently there has been an effort in the development of new composite materials possessing combined properties of high heat conductivity and friction resistant. In this study developing a composite material with such properties using underwater shock wave was attempted. Underwater shock wave can be used to penetrate hard powders into a metal base without decomposition of the base material. In this method, hard powders are penetrated into a soft metal base to obtain a composite with improved surface properties. The purpose of this research is to clarify the experimental conditions for obtaining a new composite material with unique properties. Attempt has been made to obtain aluminum-based and magnesium alloy-based composites by introducing micro/nano-sized diamond particles to the surface of the base metal. The recovered samples showed improvement of wear resistance.
