日本神户制钢所研究出锌镁合金的真空电镀法。采用这种方法生产的锌镁合金电镀钢板,与常用的镀锌钢板相比,防锈能力提高了20倍。日本使用的镀锌钢板有90％以上是纯锌电镀钢板,主要采用电镀法和热镀锌法生产。如果采用锌电镀法来电镀锌镁合金钢板,由于铝或镁离子的水溶液在电解时电子很容易和氢离子结合,因此很难电镀;若采 Japan’s Kobe Steel developed a zinc-magnesium alloy vacuum plating method. The zinc-magnesium alloy plated steel produced by this method has a 20 times improvement in the anti-rust ability compared with the commonly used galvanized steel. More than 90% of galvanized steel used in Japan is pure zinc plated steel, which is mainly produced by electroplating and hot dip galvanizing. If zinc electroplating is used to electrogalize a magnesium-zinc alloy steel sheet, it is difficult to electroplate because the electrons in the aqueous solution of aluminum or magnesium ions are easily combined with hydrogen ions during electrolysis;
