Application of laser cladding in key friction pair of hydraulic motor
激光熔覆在液压马达关键摩擦副中的应用

摘要

通过对激光熔覆铝青铜试块与锡青铜试块两组材料进行化学成分、金相组织、剪切强度、磨损等对比试验，分别了解激光熔覆与基体的结合力与耐磨性。结果表明，激光熔覆铝青铜材料性能优于锡青铜，锡青铜的结合力和耐磨性均有明显提高。

Abstract

The chemical composition, metallographic structure, shear strength and wear of laser cladding aluminum bronze specimen and tin bronze specimen were compared, the adhesion and wear resistance between laser cladding and substrate were studied. The results show that the performance of laser cladding aluminum bronze is better than that of tin bronze, and the adhesion and wear resistance of tin bronze are obviously improved.
