| 摘 要： | 利用ＳＥＭ对实际使用时断裂的髋关节的断口和表面进行了分析，认为此关节的断裂为以弯曲应力为主的腐蚀疲劳断裂。疲劳裂纹首先在表面的腐蚀点孕育产生，应力和腐蚀的共同作用使得裂纹得以扩展断裂。

| Abstract: | The fracture surface of a cast stainless steel hip joint fractured in-vivo and its normal surface were studied by SEM method. It was concluded that the fracture was corrosion fatigue crack due to the bending stress. The corrosion fatigue crack which initiated from corroded place propagated and fractured because of co-effect of corrosion and stress. |
