把裂尖表面形变动力学和裂尖表面析氢反应电化学动力学相结合，对裂尖表面析氢反应的波形效应进行了定量分析．把裂尖形变动力学与位错运动动力学相结合，提出了氢的接力式位错输送概念，并建立了波形效应的位错输氢模型．用上述定量模型与理论对正锯齿波、三角波和负锯齿波三种波形的腐蚀疲劳裂纹扩展速率的相对大小进行了预测．为验证上述模型，还用疲劳测试和断口分析方法研究了三种波形对ＧＣ－４（４０ＣｒＭｎｓｉＭｏＶＡ）钢在３．５％ＮａＣｌ溶液中的腐蚀疲劳裂纹扩展特性的影响．试验结果与模型预测结果十分吻合．
The surface deformation kinetics of crack tip and the electrochemical reaction of hydrogen evolution on crack tip are combined to analyze the wave effect of hydrogen evolution on the crack tip. Combining the crack tip deformation dynamics and dislocation kinematics, a new concept of hydrogen relay dislocation transport was proposed, and a dislocation hydrogen transport model of wave effect was established. The relative sizes of the corrosion fatigue crack growth rates of the positive, negative, and positive sawtooth waveforms were predicted by the above quantitative models and theories. In order to validate the above model, the effects of three waveforms on corrosion fatigue crack growth of GC-4 (40CrMnsiMoVA) steel in 3.5% NaCl solution were also studied by fatigue test and fracture analysis. The test results are in good agreement with the model predictions.
