Article Preview

The influence of the content of rare-earth La on the microstructure and corrosion-resistance of hot-dipped aluminum was studied in this paper .The results show that ,under the same technology conditions, the thickness of hot-dipped aluminizing layer by adding the appropriate content of rare-earth La is about 2~3 times as much as that without rare-earth La, and the microstructure of hot-dipped aluminizing layer has also greatly changed ,and a great deal of phase Fe3Al was precipitated along the boundary of a phase. The corrosion resistance of the hot-dipped layer with rare-earth La is greatly increased.
