摘要

The influence of an aggressive environment (NaCl 3.5% aerated solution) on fatigue crack initiation and crack growth behavior were studied. This study comprised corrosion fatigue tests using specimens of SAE 8620 steel. The decreasing cyclic frequency (60Hz to 11.7Hz) effect on corrosion fatigue crack initiation behavior was examined. The tests carried out under rotating-bending loading conditions at 11.7Hz (700rpm), showed that pitting corrosion caused by anodic attack was responsable for corrosion fatigue crack initiation.
