Black oxide is impregnated using oil and wax to achieve maximum corrosion resistance. With this special chemical and heat it turns black instead of red.

It is used for ferrous materials zinc copper and its alloys silver solder and powdered metals.

Black oxide rust protection. It looks great but provides no corrosion protection of any kind. Iron oxide rust is what happens normally. Black oxide is actually a form of rust.

Finally before packing the product its teeth are coated with wax. Black oxide does not effect the dimension of the part. If its going outdoors go with black zinc.

Black oxide has a range of unique properties and benefits that can be applied to a variety of industries. Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance and minimize light reflection. Its controlled with a chemical that allows the formation of oxide rust.

The bottom line is this. The corrosion resistance properties may be enhanced significantly by adding a supplemental corrosion inhibiting treatment. Black oxide coatings can be limited in their ability to provide corrosion protection in mildly corrosive environments.

Blackening remains even after cutting operation after blackening wd 40 linked by editor to product info at amazon is applied for rust prevention. Ever tried to get rust of something made of steel. Black oxide is often used to provide shelf life corrosion protection for parts in storage.

I believe it is essentially ferrous oxide which is black rust. An important property of black oxide unlike some electroplated finishes is that white rust does not form over time on the finish. But the basic coating isnt protective.

Post treatment with a mineral oil or the equivalent provides a modicum of corrosion protection and a little gloss. Alone black oxide offers only a very mild corrosion resistance. Black oxide is a conversion coating formed by a chemical reaction formed when parts are dipped into an alkaline salt solution.

A standard black oxide is magnetite fe 3 o 4 which is more mechanically stable on the surface and provides better corrosion protection than red oxide rust fe 2 o 3modern industrial approaches to forming black oxide include the hot and mid temperature processes described below. Applying a supplementary post treatment after the black oxide finish is commonly used to increase the corrosion protection properties of black oxide coatings. This is then sent for black oxide now since it is a cutter so our basic requirement is adhesion ie.

If its going indoors black oxide should be fine. But even with oil or wax black oxide only offers moderate protection and as such is ideally suited for indoor applications. If it is on a rifle which will be regularly cleaned and oiled it will probably work since teh black oxide fasteners were oiled to begin with.

If rust or scale is present on the part additional steps such as acid pickling or alkaline de scaling may have to be added before oxiding. Any tooling that will be hit with oil should be fine too. Additional treatments like oil or wax are needed for corrosion resistance.
