Black oxide does not effect the dimension of the part. Black oxide is actually a form of rust.

With this special chemical and heat it turns black instead of red.

Black oxide rust protection. Black oxide has a range of unique properties and benefits that can be applied to a variety of industries. It is used for ferrous materials zinc copper and its alloys silver solder and powdered metals. Post treatment with a mineral oil or the equivalent provides a modicum of corrosion protection and a little gloss.

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. The bottom line is this. If its going outdoors go with black zinc.

Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance and minimize light reflection. Black oxide coatings can be limited in their ability to provide corrosion protection in mildly corrosive environments. The corrosion resistance properties may be enhanced significantly by adding a supplemental corrosion inhibiting treatment.

An important property of black oxide unlike some electroplated finishes is that white rust does not form over time on the finish. Any tooling that will be hit with oil should be fine too. Its controlled with a chemical that allows the formation of oxide rust.

Ever tried to get rust of something made of steel. But the basic coating isnt protective. Blackening remains even after cutting operation after blackening wd 40 linked by editor to product info at amazon is applied for rust prevention.

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. Finally before packing the product its teeth are coated with wax. But even with oil or wax black oxide only offers moderate protection and as such is ideally suited for indoor applications.

This is then sent for black oxide now since it is a cutter so our basic requirement is adhesion ie. It looks great but provides no corrosion protection of any kind. I believe it is essentially ferrous oxide which is black rust.

Black oxide is often used to provide shelf life corrosion protection for parts in storage. If its going indoors black oxide should be fine. Alone black oxide offers only a very mild corrosion resistance.

Applying a supplementary post treatment after the black oxide finish is commonly used to increase the corrosion protection properties of black oxide coatings. Iron oxide rust is what happens normally. Additional treatments like oil or wax are needed for corrosion resistance.

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. Black oxide is impregnated using oil and wax to achieve maximum corrosion resistance. Black oxide is a conversion coating formed by a chemical reaction formed when parts are dipped into an alkaline salt solution.
