摘　　要：在渗铝工艺中加入适量的稀土元素,可有效提升钢材的抗氧化性、耐腐蚀性和耐磨性等。目前,稀土在渗铝工艺中的应用越来越广泛。分析了稀土元素在渗铝中的促渗机理。介绍了渗铝工艺中稀土元素渗入量的研究进展。综述了稀土元素对渗铝钢材性能的影响,同时对稀土元素在渗铝中的应用提出展望。Adding proper amount of rare earth elements in the aluminizing process can effectively improve the oxidation resistance, corrosion resistance and wear resistance of steel. At present, the rare earth elements are more and more widely used in aluminizing process. The permeation mechanism of rare earth elements in aluminizing process is analyzed. The research status of RE permeation amount in aluminizing process is introduced. The effects of rare earth elements on the properties of aluminized steel are reviewed, and the application of rare earth elements in aluminizing is prospected.
