许多表面处理和防护涂层在接触机械零件的耐磨性中起到很重要的作用,但是对于工作在苛刻磨损条件下或极易变形的许多构件,用传统涂复技术便不能满足要求。因此,自74年开始了激光涂复的实验研究。 Many surface treatment and protective coatings play an important role in the wear resistance of mechanical parts, but many are not able to meet the requirements of many components that work in harsh or extremely deformable conditions. Therefore, experimental studies on laser coating have been carried out since 74 years.
