alocrom 1200Conversion 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, phosphate conversion coatings and¬†black oxide coatings on steel. 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″. Thick coatings, up to 0.002″, are usually built up on aluminium alloys, either by anodising or chromate conversion.
