Abstract

The hot-dipping Al coating was developed on 22MnB5 steel surface. Effects of heat input with different welding parameters were investigated in this paper. It describes an approach to optimum the heat input of Al coating on 22MnB5 steel. The results of optimum heat input show that ~3840J/cm has the best tensile strength, whose corresponding welding parameters are optimum for hot-dipping Al coating steel. The proper hot-dipping time (~2min) of Fe-Al compounds between Fe substrate and Al coatings must be selected (750 °C, hot-dipping 2min) in order to decrease the finger-like growth of 22MnB5 steel surface coatings.
