中文摘要：
铝合金的腐蚀行为 1060 并且在 10 公里 Na2SO4+5 公里 KI 答案的 2A12 被扫描电气化学的显微镜学(SECM ) 并且扫描电子显微镜学(SEM ) 调查。潜在的地形学和腐蚀形态学结果证明样品的潜力随沉浸时间的增加出现在一样的区域变化上。腐蚀区域变得大，并且潜力变得更否定。2A12 合金表面的腐蚀潜力比 1060 铝的，和 2A12 合金容易成为腐蚀剂低。这是在一些金属间化合的粒子(淘气鬼) 的边界区域的那优先的溶解发生的原因，因为不同潜力，不同溶解行为与淘气鬼的不同类型被联系。
英文摘要：
The corrosion behavior of aluminum alloys 1060 and 2A12 in a 10 mM Na2SO4＋5 mM KI solution was investigated by scanning electrochemical microscopy （SECM） and scanning electron microscopy （SEM）. The potential topography and corrosion morphology results show that the potential of the sample surface over the same area changes with the increase of immersion time. The corrosion area becomes large, and the potential becomes more negative. The corrosion potential of the 2A12 alloy surface is lower than that of 1060 aluminum, and 2A12 alloy becomes easily corrosive. This is the reason that preferential dissolution in the boundary region of some intermetallic particles （IMPs） occurs and different dissolution behaviors are associated with different types of IMPs because of different potentials.
