The black oxide process is a chemical conversion coating. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating. Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution.
Understanding Honing Compound
A chromium oxide and aluminum oxide compound in a wax bar, it is fast and effective for polishing to a mirror finish. A 6oz bar goes a long way, providing years of use. I can personally attest that my own has lasted many years and still has plenty left.
