摘要：
In the present study, an integrated layer of iron aluminides of FeAl and Fe(3)Al was formed on the surface of a low carbon steel sheet by a two-step process. The first step was hot dipping of the steel in a molten aluminum pool and secondly laser surface processing using a pulsed Nd:YAG laser. The corrosion resistance of the coated specimens was evaluated by activation polarization and Tafel methods. The results show that laser processing of the aluminized steel leads to a considerable increase in its corrosion resistance compared to both uncoated and merely aluminized materials.
