the result show that the size of equivalent initial surface crack is less than 19.7to 22.5 percent of surface corrosion pit size which have the same life.
the check and the analysis of the pattern of corrosion pit indicated that it was pit corrosion.
对支撑梁蚀坑形貌的检查和分析表明该腐蚀为小孔腐蚀。
the correlation between corrosion pit with equivalent initial surface crack;
叶片表面的腐蚀坑是其疲劳断裂的另一促进因素。
at potentials above a critical potential that is well below the pitting potential measured from the surface covered with oxide film, corrosion pit would occur on the freshly generated surface.
