摘　　要：对稀土铝合金的热浸镀渗工艺及渗铝后的耐腐蚀性进行了研究。结果表明 ,稀土对于热浸镀渗铝具有良好的催渗作用。钢表面热浸镀渗稀土铝后 ,具有良好的耐腐蚀性 ,其中含 0 .3% L PC混合稀土的铝合金具有更好的耐腐蚀性 ,其耐腐蚀性This paper deals with the hot dipped rare earth aluminium technology and the corrosion resistance of the diffused-aluminized layer. The results show that the rare earth plays an important catalytic role in hot dip aluminized. Rare earth obviously increase the corrosion resistance of hot dipped layer,in which the 0.3% LPC rare earth content is excellent, and the corrosion resistance is about 3 times as much as the true aluminium.
