摘要

镁合金具有密度小，比强度高和生物相容性好等优点，然而，表面性能不佳限制了其进一步应用。通过表面改性技术提高镁合金的耐腐蚀性和耐磨性可扩展镁合金的应用范围。激光技术在镁合金的表面改性中效果显著，得到广泛应用。主要介绍激光熔凝、纹理化和熔覆等几种典型镁合金表面改性技术，从激光 – 合金相互作用、微观组织结构的演变规律出发，分析表面性能增强机理。

Abstract

Magnesium alloys have the advantages of low density

high specific strength and good biocompatibility

but its poor surface properties limit their further use. Improving corrosion resistance and wear resistance of magnesium alloys through surface modification techniques can expand the application of magnesium alloys. Laser techniques have a significant effect on the surface modification of magnesium alloys and thus being widely used. This paper mainly introduces the three typical laser surface modification techniques including laser surface melting

surface texture and surface cladding. It will analyze the mechanism of surface performance enhancement from the laser-alloy interaction and the evolution of microstructure.
