镁合金表面处理技术的进展

Progress of surface treatment for magnesium alloys

综述了镁合金的常见腐蚀类型及表面处理技术的常用方法。腐蚀类型主要有电偶腐蚀、点蚀、应力腐蚀等;而表面处理技术主要包括化学氧化、阳极氧化、微弧氧化、电化学镀、涂覆等。对这些技术中存在的不足以及未来发展趋势进行了分析与预测。

Common types of corrosion and common methods of surface treatment of magne- sium alloys were reviewed. Main corrosion types included galvanic corrosion, pitting corro- sion, and stress corrosion, etc. Surface treatments included chemical oxidation, anodic oxida- tion, micro-arc oxidation, electrochemical plating, and coating, etc. Shortcomings and future development of these technologies were also analyzed and predicted.
