Abstract The microstructure and corrosion resistance to salt spfay and salt water immersion (3% NaCl) of batch hot dip aluminized coatings containing Si and RE were studied. The tests indicated that addition of 1-7% Si and 0.05- 0.35% RE into the melted Al bath markedly improved the corrosion resistance of the coatings. But excessive RE would impair the improvement. With increasing temperature of salt water the corrosion rate of both Al coating and Al alloy coatings containing Si and RE increased remarkably, and for the Al alloy coatings the increase in corrosion rate was less than that for Al coating. The beneficial function of Si and RE in the corrosion resistance of the coatings was discussed.

Key words: Hot dip aluminizing Salt spray corrosion Salt water corrosion Rare earth
