Abstract：Phytic acid,an innoxious and organic phosphate,is separated from cereal crops.Owing to fast reaction with many metal ions such as Ca2+,Mg2+,Fe2+ and Zn2+ to form chelate compounds,phytic acid can be used in protection of metals.This paper reviews the applications of phytic acid in conversion coating and anodizing on magnesium alloys.As an environmentally friendly and effective treating agent,phytic acid has a good application prospect in protection magnesium from corrosion.
