Abstract:

The aluminum alloy 5052 was subjected to reverse bending fatigue in 3.5 aqueous NaCl under controlled potential. Under anodic polarization a low lifetime was observed, independent of potential under cathodic polarization lifetime increased with increasing negative potential. Maximum lifetime observed was similar to that seen in distilled water. Lifetime without specimen potential control was only slightly higher than that seen under anodic polarization. A comparison is made to published stress corrosion data. Author
