Black Oxide - The Lindgren Group

Overview Black oxide, also known as gun bluing, is a conversion coating formed by a chemical reaction produced when parts are immersed in the alkaline aqueous salt solution operated at approximately 285-295 degrees F. The reaction between the iron of the ferrous alloy and the hot oxide bath produces a magnetite (Fe3 O4) on the actual surface of the part.

Do-It-Yourself Cold Blackening : Modern Machine Shop

Both protect ferrous materials equally. This is determined by standard tests that subject a black oxide finish to 200 hours of neutral salt spray or several hundred hours of humidity. Basically, the blackening process choice for shops is hot or cold. Hot oxide uses a caustic soda bath operating at 285 to 290oF.

Do it yourself black oxide - practicalmachinist

Dec 11, 2008 · Nit: black oxide isn't "plating," it's controlled rusting to produce a particular oxide of iron that happens to be black instead of orange. My understanding is that the "cold" black oxide isn't as durable as the hot-dip process. It works though, assuming you have good surface prep, and it may be good enough for your needs.

What is Black Oxide? | Cleveland Black Oxide

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 ...

What is Black Oxide? - Definition from Corrosionpedia

When the cold black oxide process is used, color variations are experienced from one part to another, with the oxide rubbing off onto hands. This does not meet military or automotive industry specifications; thus, is not commonly used. The steps involved in the conversion coating are cleaning, rinsing, black oxide and after-finish.
