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 Fe 2 O 3. Modern industrial approaches to forming black oxide include the hot and mid-temperature processes described below. Traditional methods are described in the article on bluing. They are ...
Fume bluing is another process similar to rust bluing. Instead of applying the acid solution directly to the metal parts, the parts are placed in a sealed cabinet with a moisture source, a container of nitric acid and a container of hydrochloric acid. The mixed fumes of the acids produce a uniform rust on the surface of the parts (inside and ...
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound.
Rust scale forming and flaking off from a steel bar heated to its forging temperature of 1200°C. Rapid oxidation occurs when heated steel is exposed to air. Rust is a general name for a complex of oxides and hydroxides of iron, [4] which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of ...
Loose or thick rust must be removed before anti-rust wax like Waxoyl or a similar product is used. [ original research? Structural rust (affecting structural components which must withstand considerable forces) should be cut back to sound metal and new metal welded in, or the affected part should be completely replaced.
