| 摘 要： | 向热镀锌（GI）（Zn-0．2％Al）锌池中加入微量单质稀土La，采用热镀锌模拟机制备含La的锌镀层。采用盐雾腐蚀试验、全浸腐蚀失重试验和线性极化试验，研究了单质稀土La元素对镀层耐蚀性能的影响。结果表明，不同的腐蚀试验结果具有很好的一致性；相对Gl镀层而言，含La镀层中的La并未明显抑制白锈的产生，但明显抑制了红锈的...

| Abstract: | Effects of lanthanum addition on corrosion resistance of hot-dip galvanized steel were investigated.The coatings containing different contents of La were prepared by hot-dipping process simulator.The corrosion resistance of coatings were measured by salt spray tests,weight loss tests and linear polarization tests.All coatings containing La had excellent corrosion resistance in three types of testing environments.The results indicated that addition of La into the galvanized coatings could not inhibit the for... |
