摘　　要：介绍了热浸镀铝技术的原理和熔剂法、森吉米尔法两种主要工艺,概括了热浸镀铝技术的研究进展和工业应用趋势,指出加入适量的稀土元素在热浸镀层中能有效地改善镀层耐蚀性、耐高温氧化性、成形性和装饰性。热浸镀铝技术将会在以下几个方面开展工作:新工艺的全面细化量化型的研究;对热浸渗原理和浸渗理论的进一步研究和探索;对稀土的作用机理的深入研究以及不断完善工艺和技术,扩大其在工业生产上的应用。A brief introduction of the principles, methods （ Cook- northnan, and Sendzimir）, research development and industrial applications of hot dip aluminizing technology was presented. It was pointed out that the addition of rare earth elements could improve the corrosion and high temperature oxidation resist- ances and the type forming and decorative performances of the coatings. The directions for the development of hot dip aluminizing technology are to further optimize the techniques and to investigate the effect mechanism of rare earth so as to extend the application fields of the technology.
