Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] Zinc is easily soluble in acid and alkali, so it is called amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will be formed on the surface of zinc. The standard electrode potential of zinc is -0.76V. For the steel substrate, the zinc coating is an anodic coating. It is mainly used to prevent the corrosion of steel. The quality of its protective performance is closely related to the thickness of the coating. Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects. After the zinc coating is passivated, dyed or coated with light protection agent, its protection and decoration can be significantly improved. [0003] Hot-dip galvanizing (hot-dip galvanizing) refers to the method o...
