Chromate Conversion Coating (also known as chromating) is a chemical process applied to metal surfaces, particularly aluminum, to improve corrosion resistance, paint adhesion, electrical conductivity, and aesthetic appeal. It's widely used in industries like aerospace, automotive, military, and electrical for parts that require protection in harsh environments. Chromate conversion coatings provide a protective layer that can also be used as a primer for further coatings or paint applications.
