Paper Title:
The Corrosion Fatigue Life Research of Shot Peening Aluminum Alloy
  Abstract

The corrosion is one kind of major damage mechanisms of airplane structure and is also one of the primary causes resulting in flight failure and disaster .The aim of this paper is to analyze the effect of corrosion time on denudation depth, mass loss and the total depth of corrosion damage. Meanwhile, the three parameters have significant influence on residual fatigue life of aluminum alloy, the residual fatigue life of the aluminum alloy is of great difference between shot peening and without shot peening aluminum alloy. Then residual fatigue life tests are carried on Instron 8801 for the shot peening and without shot peening aluminum alloy. Based on contrast analysis of the experimental results, valuable conclusions are obtained: with the increase of the denudation depth, mass loss and the total depth of corrosion damage, fatigue life reduce continuously respectively; Fatigue life decreases rapidly when the denudation depth is in the range of 0.12~0.17mm.
