Effect of Typical Corrosion Damages on Structural Material Characters

The effect of pitting corrosion and exfoliation corrosion on material degradation and fatigue life was investigated.Based on the experiments,the theoretical model and histogram of material degradation extent induced by pitting corrosion and exfoliation corrosion were presented.The effect of pitting corrosion and exfoliation corrosion on fatigue life of structural materials was analyzed using the AFGROW software and the predicted results were in good agreement with experimental cycles.
