The Surface of Wearing of the Die & Mould Wear Self-repair'sSynthesize with Restoring ZHANG Jin 1,SUN Zhi-fu 2,Xia Hua 1,ZHAO Wei-ling 1,HU Ya-min 1(1.School of Materials Science and Engineering, Chongqing Institute of Technology, Chongqing 400050, China;2.School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China)This paper studied the theory of die & mould wears self-repair of the mechanical parts. The main elements of the metal wear self-repair material (ART) were screened. The mixture was prepared in mechanic chemosynthesis to the self-repair pottery surface in the help of chafe heat after the selected mineral powder was mixed with the engine oil dry-friction in the friction chafe. And the basic principal has synthesized and the self-repair pottery surface appearance was discussed.wear; self-repair; pottery surface; synthesize with restoring
