金属材料表面改性处理的研究与开发已列入“八五计划”期间国家科技攻关重点项目。目标是:通过激光、离子注入、真空蒸镀、复合处理等表面改性处理方法,使这种高技术处理在冶金系统形成一定的规模产业,以使各种机械转动零部件的使用期限在目前的2000小时基础上提高2～3倍,使凸轮轴、曲轴、缸体、模具等的表面洛氏硬度HRC≥60,耐磨性
The research and development of the surface modification of metal materials have been included in the national key scientific and technological projects during the “Eighth Five-Year Plan”. The goal is to make such high-tech processing a certain scale industry in the metallurgy system through laser, ion implantation, vacuum evaporation, complex treatment and other surface modification methods so as to make the service life of various mechanical rotating parts at present 2000 hours on the basis of 2 to 3 times increase, so that the camshaft, crankshaft, cylinder, mold and other surface Rockwell hardness HRC ≥ 60, wear resistance
