What is conversion coating?

Conversion coating is a chemical process applied to metal surfaces to create a protective layer that enhances corrosion resistance and paint adhesion. The process involves treating the metal, such as aluminum or steel, with specific chemicals to convert the surface into a thin, inert coating. Common types include phosphate, chromate, and anodizing treatments. Conversion coatings are widely used in industries like automotive, aerospace, and manufacturing to increase the lifespan and performance of metal parts.
