Diy Black Oxide Coating

Aside from aesthetics it does make parts look nice the black deposit on the workpiece is actually a means to hold a sealant which is the business end of blackening.

Diy black oxide coating. Black oxide gel kit. One of its advantages over other coatings is. To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. Simply apply the black oxide gel where you want the blackening to occur.

It is an activator for use before blackening. Seal with caswell sealer for a dry. Hot black oxide converts the surface into magnetite. The gel keeps the blackener in place.

Normal oxide coating was done with heat and chemical baths that still could not prevent the corrosion over time. The cold processes produce a similar color but the coating tends to rub off more easily and offer less abrasion resistance. The black oxide finish makes the metal surface porous enabling it to hold a thin layer of oil. The metal blackening system was designed for the diy market to accurately duplicate the look and feel of black oxide phosphate finishes on automotive under hood and under car hardware bracket hinges etc.

Black oxide is a finish applied to ferrous metals that provides rust protection. It is used to add mild corrosion resistance for appearance and to minimize light reflection. Black oxide activator 1 quart makes 2 5 gallons black oxide activator product does not perform blackening. It s the oil that prevents rust from forming on the metal.

The application of oil wax or lacquer will bring the corrosion resistance up to par with the heated processes. Easily spot blacken steel not stainless or iron. Black oxide is a conversion coating formed by a chemical reaction produced when parts are immersed in the alkaline aqueous salt solution operated at approximately 285 degrees f. The sealant usually oil finds its way into the pores of the black oxide coating where it is held in close contact with the metal substrate.

Certain hardened or specialized steels can prove challenging to blacken with our black oxide solution only blackening to a grey color. If you want to make a black oxide finish yourself the cold process black oxide system is a safe alternative.
