| 摘 要： | 研究了在3.5%NaCl水溶液(质量分数,下同)中性盐雾环境中,带有局部包铝层的2024和7B04高强铝合金轴向疲劳板材光滑试样的腐蚀.发现疲劳试样表面的局部包铝层不仅保护其覆盖区域不被腐蚀,同时也间接减轻了其未覆盖区域的腐蚀程度.这主要是由于局部包铝层的存在减小了其未覆盖区域的腐蚀面积,而铝合金腐蚀面积的减小会造成腐蚀程度降低.腐蚀面积的变化对2024铝合金影响较小,造成腐蚀深度的减小;对7B04铝合金影响较大,可以使其不发生点腐蚀.

| Abstract: | The pitting of 2024 and 7B04 aluminum alloy plate fatigue samples with partial aluminum clad in 3.5% NaCl NSS(Neutral Salt Spray Test) was investigated.It was found that the partial aluminum clad not only protected the covered area from corrosion but also decreased the pitting probability of uncovered area indirectly,because the reducing of corrosion area decreased the pitting probability of aluminum alloy.As the area reduced,the pitting expansion of 2024 aluminum alloy samples slowed and the pitting probab... |
