The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of hot, molten zinc. Se mer The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to … Se mer Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item. In the case of automobile bodies, where additional decorative coatings of paint will be applied, a thinner form of galvanizing is applied by electrogalvanizing. … Se mer In the early 20th century, galvanized piping replaced previously-used cast iron and lead in cold-water plumbing.
