Oxidized galvanizing has the advantages of good dispersion ability and deep plating ability, fine crystallization, good bonding force with the substrate, good corrosion resistance, wide process range, stable and easy-to-operate plating solution, and less sensitive to impurities. However, it is highly toxic and seriously pollutes the environment. Now most of the application of oxygen-free galvanizing, or low-oxygen galvanizing.

The bath composition of zinc oxide plating: A, zinc oxide; B, sodium oxide; C, sodium hydroxide; D, brightener for zinc oxide plating.
