| 摘 要： | Influence of applied potentials and loading waveform on the fatigue crack growth forsteel A537 in 3.5% NaCl solution,and corresponding straining electrode behaviour havebeen studied.Under the applied potentials over or below -800mV(SCE),the anodicdissolution or the hydrogen embrittlement is predominatant,respectively.For appliedanodic potential,the acceleration effect of continuous loading pattern on the CF crackgrowth mainly appeared at the range of low ΔK values,while for cathodic potential,itappeared at the high ΔK values.The continuous straining causes a decrease of naturalpotential and an increase of anodic dissolution current.
