Rust converter. Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides (rust) 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 ...
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 time. Over time, the oxygen combines with the metal ...
Bluing, sometimes spelled as blueing, is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish. Bluing involves an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the ...
From powerful and corrosive to gentle and nontoxic, these liquid and powder rust removers can restore tools, cars and home fixtures with minimal effort.
Conversion coating. 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. These coatings are commonly applied to protect the part against corrosion, to improve the adherence of other coatings, for lubrication ...
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates, to achieve corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. [1][2][3] It is one of the most common types of conversion coating.
