摘要 综述了激光在镁合金加工中的应用现状,介绍了镁合金激光加工设备、工艺技术,并对镁合金激光加工技术的发展进行了展望。激光焊接可以获得组织细小、性能优良的镁合金焊缝;激光表面熔凝、合金化以及激光熔覆等表面改性工艺可提高镁合金的硬度、耐磨性和耐腐蚀等表面性能;激光切割可以实现镁合金的高速高质量切割加工。因此,镁合金的激光加工技术具有广阔的应用前景。 The status of laser application in processing of magnesium alloys was systematically reviewed.The equipment and technology for laser processing of magnesium alloys were introduced as well as the development prospects of the laser processing technology.Laser welding can result in the welding joint with fine microstructure and good properties.The laser surface modification techniques such as laser surface melting,laser alloying and laser cladding can improve the surface properties such as hardness,wear resistance and corrosion resistance of the alloys.Laser cutting can achieve high-quality and high-speed machining of the alloys.Thus,the laser processing technology for magnesium alloys will have a wide application in the future.
