The high temperature oxidation behavior and alloying reaction of hot-dip Zn-Al coating on Mn-B steels during hot stamping was investigated in detail. The results show that the oxidation behavior depends on the atomic ratio of Al/(Zn + Fe) around the surface of the coating. Furthermore, a preheating treatment at 550°C can increase the atomic ratio of Al/(Zn + Fe) on the top surface due to the high affinity between aluminum and oxygen, which, in turn, improves the high temperature oxidation resistance.falsehot stampinghot-dip Zn-Al coatingLMIEoxidationconference paper2-s2.0-85197479555
