摘要:
研究了添加稀土镧对热浸镀渗铝钢渗层的组织和耐H2S腐蚀的影响，结果表明随着稀土含量的增加，渗层中富铝层增厚。当稀土添加量由0％升至0．3％时，渗层的耐蚀性逐渐提高，当稀土添加量大于0．3％时，渗层的耐蚀性反而逐渐降低。添加0．3％稀土渗层的耐腐蚀性能最好，为不加稀土的2．5倍。

The Influence of Rare Earth Lanthanum on the Corrosion-resistance to H2S of Aluminum Hot-dipped Steel
HU Peng-fei1，WEN Jiu-ba2，ZHANG Wei1
Abstract:
The influence of rare earth lanthanum on the microstructure and corrosion-resistance to H2S of hot-dipped Aluminum was studied. The results showed that the rich aluminum layer in the Aluminum hot-dipped steel becomes thicker with the increase of the rare earth content. The corrosion-resistance is enhanced when rare earth is added from 0 % to 0.3 %, butbestit is decreased when rare earth content exceeds 0.3corrosion-resistance, about 2.5 times as high as that%. The aluminum hot-dip process with 0.3 % rare earth showed the without rare earth.
Key words:  rare earth  hot-dipped aluminum  corrosion  corrosion-resistance
