conversion coating

Conversion coating is a protective treatment applied to metal surfaces to improve corrosion resistance and prepare for painting or coating. It involves chemically reacting with the metal to form a thin, stable layer that seals the surface and prevents rust. Common types include chromate, phosphate, and oxide coatings. These coatings enhance durability and adherence of paints or other finishes, extending the lifespan of metal parts in various industries like automotive, aerospace, and manufacturing. The process is an efficient way to protect metals without significantly changing their shape or size.
