Abstract

Conversion coatings containing hexavalent chromium (chromate) have been widely used for decades as part of corrosion protection systems on aluminium alloys. However, chromates are prohibited in many fields due to their toxicity and should be replaced by “green” environmentally friendly alternatives. Cerium-based conversion coatings (CeCCs) are among the most prospective alternatives because of their anticorrosion efficiency, environmentally friendly characteristics, and low cost. This review is focused on the protective properties of CeCCs on aluminium as a sole protecting coating or as a conversion one in combination with top organic coating.
