Purpose: Galvanic galvanizing of cast iron protects it from corrosion in atmospheric conditions and neutral, non-salty environments. The final rainbow chromatization increases the protective properties of the entire coating several times. Only olive chromate provides the best protection. Cast iron products are more difficult to process than steel products. This is due to the presence of a casting crust on them, the quality of which (density) can vary greatly. Cast irons with a porous casting skin are more difficult to coat. Also, on cast iron, the overvoltage of hydrogen evolution is lower, which facilitates this negative side reaction during alkaline galvanizing, unless special additives are used in the electrolyte.
