On March 14, 2014, the Jiangsu science and technology support program, which called ”High performance camshaft of laser micro processing composite processing technology and equipment research”, beared by the surface and interface science and technology institute of Jiangsu University and Jiangsu Wansheng Foudry co., LTD , had been checked and accepted by the expert group in Changzhou, Jiangsu province. The research results of this project has great importance in realizing engine critical friction pair micro processing composite processing, improving camshaft friction pair of anti-friction and anti-wear performance, and promoting the development of texture surface tribology .
