激光熔敷合金层组织与高温磨损性能的研究

Microstructure of Laser Cladding Alloy Layer and Abrasive-wear Behavior Under High Temperature

通过显微组织观察及不同成分、不同温度下的高温干摩擦磨损试验 ,对激光熔敷合金层高温干摩擦磨损性能进行了研究。结果表明 ,Ni2 1+2 0 %WC +0 5 %CeO2

The microstructure of the laser cladding alloy layer and its abrsrsive-wear behavior under high temperature by changing composition and temperature were investigated.The results showed that Ni21+20%WC+0.5%CeO 2 cladding layer presents the best abrasive-wear behavior under high temperature in these investigated coatings.
