[0002] Steel is the most widely used metal in the world. However, steel is easy to rust in air, water or soil, that is, it is easy to corrode. In order to reduce the corrosion of steel, people have adopted a variety of anti-corrosion methods, among which the method of coating a protective layer on the surface of steel is the most common method. Since zinc has good corrosion resistance in the atmosphere and is a relatively cheap metal, the cost of protecting steel with a zinc layer is relatively low, which has also promoted the development of the hot-dip galvanizing industry and has become the most widely used metal rust prevention method.
