Examples of 'conversion coatings' in a sentence
Meaning of "conversion coatings"
conversion coatings: Conversion coatings are chemical treatments applied to metal surfaces to enhance corrosion resistance, paint adhesion, and other properties. These coatings involve a chemical reaction between the metal surface and the coating compound, resulting in a protective layer
