The corrosion failure of Ni-P alloy plating was mainly caused by pitting and the process can be divided into initial stage of corrosion, propagation stage and penetration stage of pitting.
结果表明，空冷器管束在失效环境中发生了腐蚀减薄和穿孔泄漏的主要原因是电化学腐蚀、坑蚀、湍流腐蚀和冲蚀以及他们的交互作用引起的。
At the initial stage, the pitting cores are formed and the passive film is repaired continuously, which results in the inductive component in the electrochemical impendence spectrum.
在初始阶段，形成的点蚀芯连续被修复的钝化膜，这会导致在电感元件中的电化学阻抗谱。
