More info

Zinc is soluble in acid and soluble in alkali, so it is called amphoteric metal. If is a steel matrix, and the coating damage or corrosion generated by Fe - zinc battery, zinc coating anode sex coating, belonging to the dissolution of zinc sacrifice, to protect the copper, iron, so the zinc coating on the steel was not a simple mechanical protection, but rather through electrochemical action to protect substrate from corrosion, even if incomplete zinc layer will play the role. Moreover, the corrosion resistance of the zinc coating is largely determined by the corrosion resistance of the passivation film on the coating, and the corrosion resistance of zinc coating is generally increased by 8~20 times.
