√The zinc magnesium alloy coating equipment of automobile steel plate has more excellent compactness, adhesion, corrosion resistance and machinability.

√The commonly used protective coating is pure zinc coating. With the development of science and technology, the advantages of zinc magnesium alloy coating are more prominent.

√The anticorrosion performance is 23 times higher than that of pure zinc coated steel plate, and the appearance is beautiful, which is popular in automobile industry.

√At present, it is the mainstream technology to obtain the zinc magnesium alloy coating by resistance evaporation or electron beam evaporation technology of vacuum evaporation coater. It has the characteristics of high film forming rate, and the prepared film is between several microns to dozens of microns.
