腐蚀斑点属于应力集中。
水蒸气老化实验：测试是否变色或腐蚀斑点，及后续的可焊性。
Water vapor aging test whether experiment: discoloration or corrosion, and the subsequent spots solderability.
腐蚀斑点还会因不同的部件、斑点的位置和循环载荷状况，导致一些不同的疲劳裂纹。
Corrosion pitting also can lead to fatigue crack initiation depending on the component, the location of pitting, and cyclic loading conditions.
用时效方法可接近的珐琅和底漆进行接触性损伤检查有助于预防腐蚀斑点的形成并减少大修工作量。
Touching up damage to accessible enamel and primer in a timely manner can prevent the formation of corrosion pits and reduce the need for excessive rework during overhaul.
在出现斑点之前去除可见的表面腐蚀(诸如c -检)有助于预防发生裂纹。
Removing visible surface corrosion before pitting begins (such as during a C-check) helps prevent conditions that can lead to crack initiation.
随后斑点穿过压缩层继续扩展，剩余应力发生改变，斑点最终导致应力腐蚀裂纹。
The pit then grows through the compressive layer, and the change in residual stress state and the pit geometry initiate stress corrosion cracking.
腐蚀和斑点。
如果出现局部损伤并发生无法避免的扩散性变形，应当按照腐蚀和斑点类似的修理方法进行修理。
If the damage is local and widespread deformations are not evident, repair may be similar to that required for corrosion and pitting.
