Acid Zinc Plating
Acid zinc plating is one of the mainstream electrogalvanizing processes. Its plating bath is acidic overall, and zinc ions are directly electrodeposited on workpieces to form zinc coatings, which distinguishes it from alkaline zincate plating with strong alkaline complexing systems.

Alkaline Zinc
Alkaline zinc plating (dominated by cyanide-free alkaline zincate plating) is one of the two major mainstream electrogalvanizing processes. The plating bath is strongly alkaline (pH＞12). Zinc ions form complex zincate ions with strong alkali, and a zinc coating is electrodeposited on the workpiece surface when energized.

zinc-Alloy
Zinc alloy plating (electrodeposited zinc alloy coatings): An alloy coating mainly composed of zinc with a secondary metal (nickel, iron or cobalt) is formed via electrolytic co-deposition on steel or iron substrates. As a high-performance sacrificial anti-corrosion coating, it serves as an upgraded alternative to conventional pure zinc plating (acid / alkaline zinc plating).
