Abstract

The hot-dipping Al coating was developed on 22MnB5 steel surface. Effects of corrosion resistance with different dipping time coatings were investigated in this paper. It is describes an approach to improve the corrosion resistance of 22MnB5 steel. The results of the polarization curves show that the dipping 2min coatings have the highest corrosion potential (Ecorr) and the lowest corrosion current (icorr), indicating that this coating is a best corrosion inhibitor. It is similar results with EIS for corrosion resistance, respectively. The proper thickness (~20μm) of Fe-Al compounds between Fe substrate and Al coatings must be selected (750°C, hot-dipping 2min) in order to improve corrosion resistance for 22MnB5 steel.
