通过比较激光熔凝、激光合金化、激光熔覆三种铝合金表面强化工艺方法的异同,阐述了用三种方法所获得的强化层的组织特征,分析了强化层的厚度、硬度及耐磨性 指出激光熔覆是提高铝合金耐磨性的最有应用前景的方法之一。
By comparing the similarities and differences between three methods of surface hardening of laser cladding, laser alloying and laser cladding, the microstructures of the strengthening layers obtained by the three methods were expounded. The effects of the thickness, hardness and wear resistance Sexually pointed out that laser cladding is one of the most promising ways to improve the wear resistance of aluminum alloys.
