摘要 将蚀坑损伤参量分成4类:尺寸、形状、统计和试验参数,回顾了蚀坑深度、投影面积、长宽比、矩形比、表面腐蚀率、分形维数、预腐蚀系数等影响剩余寿命的主要损伤参量,总结了蚀坑等效成初始裂纹的方法. This paper sorts pit damage parameters into tour caregorms:size,shape,statistical and eters, reviews the key damage parameters that affect the residual fatigue life most such as pit depth, projection area, aspect ratio, rectangular ratio, corrosion area ratio, fractal dimension and pre-corrosion coefficient, and summarizes the methods to equal pit as an initial crack.
