采用过渡层／主体镀层／封闭层的三层结构做耐热合金的防护层。以冲击镍做过渡层提高基体材料与镀层的结合力；主体镀层含陶瓷粒子的复合镀层；经激光处理将表面重熔封闭。经实验证明，防护层有优良的耐高温氧化、含硫（０．５Ｍ）介质腐蚀性能以及振动磨损等性能
The transition layer / the main coating / closed three-layer structure to do the heat-resistant alloy protective layer. The impact of nickel to do the transition layer to improve the bonding strength of the substrate and the coating; the main coating containing ceramic particles composite coating; the surface of the laser remelting closed. Experiments show that the protective layer has excellent high temperature oxidation, sulfur (0.5M) medium corrosion properties and vibration and wear properties
