Black Oxide - JSA

The TruTemp® process operates effectively at much lower temperatures than ordinary black oxide- 100 degrees lower, in fact! The result is a protective black finish-.000020" (1 micron) thick, with an attractive satin black appearance equal to that of regular black oxide. Safe. Easy to Operate. No Boiling Chemicals Let's face it.

What is Black Oxide? - Premier Finishing

Hot black oxide is a conventional hot (285 F˚) process which produces a true black oxide iron magnetite. All the benefits of black oxide are available from the "hot" oxidizing process. A black oxide coating can be formed in either a hot or cold solution. The "cold" black oxide process, applied at room temperature or slightly elevated ...

Black Oxide and Cold Blackening FAQs - Finishing

Black oxide is a finish applied to iron and steel. There is also a ' black oxide' process applied to the copper inner layers of printed circuit boards, but that is another topic. There are two general types of black oxide for iron and steel: hot black oxide (or hot blackening) and room temperature blackening (or cold blacking). Hot blackening:

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.

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.

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.
