A Review of Hot Dip Aluminizing on Steels

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.
