A chemical conversion coating is a treatment on metal surfaces that causes a chemical reaction at the metal’s surface. This chemical reaction makes the metal surface a thin layer of protection. In contrast to anodizing, which results in non-conductive coatings, chemical conversion coating also maintains electric conductivity.
Chemical conversion coatings are more economically produced than anodizing because they don’t require electricity. Depending on your choice, it can be either colored or transparent. Chromatizing and chromate conversion are further terms for a chemical conversion coating.
Due to various significant benefits over other existing coating techniques, the chemical conversion coating technology has been widely used to cover ordinary metallic materials to prevent corrosion.
In general, this wet-coating technique produces a layer that covers the surface of components consistently, even those with irregular geometries, such as porous, hollow, and screwed constructions. Heat sinks, vehicle wheels, and typical aluminum hardware and components all require chemical conversion coatings.
Chemical conversion coatings are utilized in aerospace applications on aircraft hulls, side and torsion struts, landing gear, shock absorbers, and flight control systems like rudder systems and wing components. The coating prevents corrosion on enclosures and metal parts and ensures that aluminum chassis and components can get dependable electrical connections.
