Abstract
The traditional chromate chemical conversion solution is usually to deal with toxic and carcinogenic hexavalent chromium,in order to protect the environment and achieve human sustainable development,the scientific and technical personnel at home and abroad make recently a lot of study for new magnesium alloys chromium-free chemical conversion coating technology to replace chromate treatment of magnesium alloy.In view of the above,this paper describes the progress and the status quo of several chromium-free chemical conversion processing technology for magnesium alloys at home and abroad,and points out the existing problems at present and the developmental prospects to this technology.
