| Abstract: | This paper sorts pit damage parameters into four categories: size, shape, statistical and test parameters, 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 coeffcient, and summarizes the methods to equal pit as an initial crack. |

| Keywords: | pit morphology residual fatigue life damage parameters pit equivalence |
