Abstract

Firstly,the reasons why magnesium and its magnesium alloys corroded and the problems faced by inorganic conversion coatings at this stage were introduced.Secondly,the results based on phytic acid,phytic acid composite membranes,polyphenolic acids,fatty acids and new polymer shells on magnesium alloys were viewed.Finally,the future development of magnesium alloy organic conversion coatings was prospected.

Key words
