Abstract

A study of the effect of the rare earth element Ce on the corrosion resistance of medium Mn-TRIP was carried out in this work. In order to elucidate the role of Ce and the corrosion behaviour of medium Mn-TRIP, the effect of Ce on the corrosion resistance of medium Mn-TRIP was investigated by neutral salt spray corrosion experiments, electrochemical experiments, and X-ray diffractometer and scanning electron microscope, respectively. The results show that the addition of Ce can reduce the corrosion rate of medium Mn-TRIP at the early stage of corrosion, increase the corrosion rate at the middle stage of corrosion, and at the late stage of corrosion, the difference in corrosion rate between the two is not significant, and the electrochemical properties of medium Mn-TRIP are less changed.
