| 英文摘要 | Based on S-N curve of corrosion fatigue (CF) for LY12CZ aluminum alloy, the tendency of CF lives of the uncoated and coated specimens in 3.5%NaCl solution was studied. The evolution of the cathodic current with cyclic number under cathodic polarization was measured. The morphology of fracture surface was observed and the mechanism of the effect of the cathodic polarization on the CF life of LY12CZ aluminum alloy with and without coating was analyzed. CF lives of the uncoated specimens were increased evidently as cathodic protection in certain range of potential restrained anodic corrosion. But the potential reached some value (exceeding -1400 mV), cathodic corrosion of aluminum alloy made CF lives obviously decrease. For coated specimens, in certain range of potential the cathodic protection did not appear due to coating. When the potential was over some value, CF lives of coated specimens were ligher than those of uncoated specimens because the coating prevent cathodic corrosion. |
