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 a rust preventive oil. No dimensional change.
Titanium Cleaning & Acid Etching - This is an Aerospace requirement from the OEMs like GEAE for P4TF3.
Sulfuric Acid- Provides thick oxide coatings for aluminum and its alloys.
