Black dye plating (treatment)
Black treatment to prevent iron from rusting.
Black dye plating (treatment) is one of the chemical treatments that involves causing a chemical change (chemical reaction) on the surface of iron through alkaline processing to dye it black, creating an oxidized film of ferric oxide, commonly known as black rust, on the surface. Black dye plating (treatment) is often used for parts where dimensional accuracy needs to be maintained or where cost reduction is desired. It not only protects the surface of metal materials but is also used for decorative purposes and to enhance light absorption properties.
