高鋁類鋁鋅鎂鍍層的附著量也有合適的范圍，如果低于20g/m2，固然耐腐蝕性能不好；如果高于130 g/m2，則會因鍍層過厚，影響產(chǎn)品的焊接和

加工性能。含鎂鍍層促進(jìn)白鈉鎂礬（Simonkolleite-Zn(OH)8Cl2H2O）的生成，穩(wěn)定的白鈉鎂礬在鍍層表面形成一層薄膜，大大延緩了鋁和鋅合金鍍層

的腐蝕反應(yīng)，同時提高鍍層中的MgZn2、Mg2Si金屬間化合物，發(fā)揮的耐腐蝕性。當(dāng)然Mg的含量越高，原板狀態(tài)下的耐腐蝕性就越高，但是Mg的增加

會導(dǎo)致合金層硬度的增加。在切割時可能會引起鍍金層變硬、涂膜層裂紋。因?yàn)榱鸭y導(dǎo)致水分浸潤，反而會加重腐蝕。

The attachment amount of high aluminum, zinc and magnesium coating is also suitable. If lower than 20g / m2, the corrosion resistance is poor, if higher

than 130 g / m2, the welding and processing performance.Magnesium plating promotes the generation of white sodium magnesium alum

(Simonkolleite-Zn (OH) 8Cl2H2O). The stable white sodium magnesium alum forms a thin film on the coating surface, which greatly delays the corrosion

reaction of aluminum and zinc alloy plating, and improves the MgZn2 and Mg2Si intermetallic compounds in the coating to exert corrosion resistance.Of course,

the higher the content of Mg, the higher the corrosion resistance in the original plate state, but the increase of Mg will lead to an increase in the hardness of

the alloy layer.When cutting may cause the gold coating hardening and coating crack.Because the cracks lead to moisture infiltration, but it will aggravate the

corrosion.
