当前的研究使用小尺寸电极研究了两种类型不锈钢上单个凹坑演化的声发射（AE）行为。在 17-4 PH 点蚀期间观察到数十个 AE 信号。然而，304 SS 的声发射性要低得多。根据原位光学观察，在17-4 PH点蚀过程中观察到黑色絮状团簇。然而，这样的过程在304 SS中非常薄弱。结果发现，凹坑内部形成的氢气气泡和凹坑周围电解质的扰动能够产生声发射信号。
The current study investigated the acoustic emission (AE) behaviour of a single pit evolution on two types of stainless steels using small-scaled electrodes. Dozens of AE signals were observed during pitting on 17-4 PH. However, 304 SS was much less acoustically emissive. According to the in-situ optical observation, black flocculent clusters were observed in 17-4 PH during pitting. However, such process was very weak in 304 SS. It was found that the hydrogen bubble formed inside the pit and the perturbation of electrolyte around the pit were able to create AE signals.
