摘要

X70 steel was heated at 1200 °C for 10 minutes, then respectively cooled by water, air and within furnace,and the different microstructure was obtained. Compared with the original microstructure, the corrosion behavior of X70 steel with other three kinds of microstructure was studied by burying them in Ku'erle soil with saturated water for 30 days. The appearance micrographs of the corrosion products were observed by SEM. The corrosion process of X70 steel samples with different microstructure was evaluated using electrochemical impedance spectroscopy (EIS) method. The experiment results show that when buried in Ku'erle soil for 30 days, the corrosion rate of X70 steel sample with original microstructure is the lowest,the corrosion resistance of X70 steel samples after heat treatment is decreased because of the change of microstructure and looseness of the corrosion products.
