钢铁表面热浸镀铝技术回顾

A Review of Hot Dip Aluminizing on Steels

综述了热浸镀铝技术的发展现状和热浸镀铝的工艺过程及特点,分析了镀铝层的结构和形成机理,阐述了镀铝层、Fe-Al金属间化合物层厚度及铝中Fe含量的控制方法,对镀铝层的表面质量控制、热浸镀铝件的主要性能特点及其热浸镀铝技术的应用都进行了介绍。

The development, prpcess, principle and characteristics of hot dip aluminizing technique are reviewed, and the microstructure and formation mechanism of Fe - Al intermetallics are analyzed. The effects of dipping temperature and time on the thickness of pure aluminum and the intermetallic layers are also discussed. Whereas, the control of iron content in aluminum melt, the quality control of the coating layer and the prpperties and applications of the aluminized steels are described.
