提出了对水腐蚀疲劳机制的批判性但非详尽的回顾，特别强调腐蚀-变形相互作用，指出了从电化学角度腐蚀疲劳裂纹萌生和扩展预测的经典方法的局限性。它显示了循环塑性变形如何局部改变电化学反应以及腐蚀（阳极溶解和/或氢效应）如何改变局部塑性和微断裂。详细介绍了检测局部腐蚀疲劳损伤的实验方法。强调了疲劳阈值附近的裂纹扩展机制，特别关注阳极溶解和氢效应以及腐蚀疲劳和应力腐蚀开裂之间的相互作用。最后提出了最近介观尺度腐蚀疲劳损伤和寿命的数值模拟，并给出了未来研究的趋势。
A critical but non exhaustive review of the aqueous corrosion fatigue mechanisms is proposed with a particular emphasis on the corrosion-deformation interactions, The limits of the classical approaches of corrosion fatigue crack initiation and propagation predictions from the electrochemical point of view are pointed out. It is shown how the cyclic plastic deformation can locally modify the electrochemical reactions and how corrosion (anodic dissolution and/or hydrogen effects) can change the local plasticity and microfracture. The experimental methods to detect the localized corrosion fatigue damage are detailed. The crack propagation mechanisms near the fatigue threshold are underlined, with a particular attention for the anodic dissolution and hydrogen effects and the interaction between corrosion fatigue and stress corrosion cracking. Finally recent numerical simulations of corrosion fatigue damage and lifetime at mesoscopic scales are proposed and trends for future researches are given.
