Conversion Coatings—A finish for zinc (clear, blue, yellow, olive drab or black), aluminum, copper, brass and bronze, which protects against corrosion.

Pickling—This is a process that removes all foreign material from the surface of stainless steel.

Passivating on Stainless Steel—This is a process that removes all foreign material from the surface of stainless steel.

Black Oxide—This is a jet-black decorative finish for iron and steel. Has some corrosion inhibiting properties in it but is usually supplemented by rust preventive oil. No dimensional change.

Titanium Cleaning & Acid Etching—This is an Aerospace requirement from the OEMs like GEAE for P4TF3.
