Abstract
The currently employed inorganic conversion coatings are unattractive and their use is restricted due to toxicity, non-biodegradability and high cost. Conversion coatings based on environmentally friendly, economic and biodegradable organic compounds is a promising alternative approach. These compounds with surface chelating functional groups can effectively bond with the magnesium/surface hydroxide layer and at the same time can provide anchoring groups for the polymer overcoat. They can act as a potential host for nanoreservoirs with loaded inhibitors for active self-healing corrosion protection. This review provides a comprehensive account of the organic conversion coatings for magnesium and its alloys.
