The fracture and the surface of a hip joint fractured invivo has been studied by SEM. It is concluded that the fracture was due to corrosionfatiguecracking by bending stress.
There are some factors which influence the characteristics of initiation and propagation of stress corrosioncracking and corrosionfatiguecracking in high-strength steel in a watery environment.
影响高强度钢在水介质中的应力腐蚀和腐蚀疲劳裂缝萌生和扩展特性的因素甚多。

Through-thickness cracking also can lead to fatigue or stress corrosioncracking of the base metal beneath the plating.
