Conversion Coating

Conversion coating is a surface treatment process that involves the application of a thin layer of a protective material onto a metal surface to enhance its corrosion resistance, adhesion, and paintability. The process involves the use of chemical or electrochemical reactions to create a layer of oxide, phosphate, or chromate on the metal surface. The coating layer acts as a barrier between the metal and the environment, preventing the metal from corroding or reacting with other substances. Conversion coating is commonly used in the aerospace industry to protect aircraft components from corrosion and wear, and to improve their paint adhesion. The process is also used in the manufacturing of spacecraft and satellites to protect them from the harsh space environment.
