本文通过对45钢不同状态的断口进行腐蚀，使用扫描电子显微镜( SEM )观察其断口形貌变化，发现：随着腐蚀时间的延长，对于退火态和正火态以及回火态的断口的断裂特征将逐渐消失；而腐蚀对淬火态的断口形貌影响较小。

The fractures in the different state of 45# steel were corroded and were observed by scan electronic microscope ( SEM ) . The results show that the fracture characteristics of annealing , normalizing and tempering steels gradually disappear with the elongation of the time . However , there are nearly no effect of corrosion on the fracture characteristics of quenching steel .
