Conversion coatings are coatings for metals where the part surface is converted into the coating with a chemical or electro-chemical process. Examples include chromate conversion coatings, bluing, oxide coatings on steel, and anodizing. They are used for corrosion protection, increased surface hardness, to add decorative color and as paint primers. Conversion coatings may be very thin, on the order of 0.00001".
