Abstract

Ever though fatigue in anodized coating on aluminum is on extremely important matter in aircraft, there have been few reports on the problem, so we studied the effect of the existence of anodic oxide film on aluminum using S-N curves determined by the rotational bending fatigue method.<br>The following results were obtained;<br>(1)The anodized coating fatigued easily on the high stress side, but not on the low stress side. On the high stress side, this was because a notching effect acted on the coating owing to the occurrence of cracks, while on the low stress side, the fatigue limit was greater than with no anodized coating because of the hardness of the oxide film.<br>(2)The rupture planes were almost, but not perfectly, directly planer.
