Abstract: 
In this research a reducing slag (NaCl-KCl-Na3A1F6-AlF6) was used for surface preparation of AISH010 steel, effect of immersion time on alloy layer thickness, layer phases and durability against corrosion at 800 °C, 30 hours investigated. The results of study show that: by making use of Na3AlF6 slag the preparation of surfaces of samples is possible, the growing up alloyed layer until 15 seconds in a melted Al is noticeable, but after 15 seconds the process is so slow. The phases of the layer before heat treatment are Fe2Al5, FeAl3 and Fe Al but after heat treatment these phases replaced by FeAl and #aFe. The results of the corrosion tests show that: the weight reduction of aluminized samples is very low in comparison to non-aluminized samples. On the other hand, the stable phase at the above condition is #aFe.
