| 摘 要： | 研究了不锈钢去膜表面在氯化镁介质中的点腐蚀现象。去膜表面发生点蚀的临界电位低于膜覆盖表面发生点蚀的临界电位。去膜表面的点蚀主要在晶界和夹杂起源。点蚀形貌是敏锐的条纹状花样。根据作者提出的裸表面与氯化物介质反应步骤模型讨论了点蚀特征电位的意义以及裸表面点蚀形成的过程。

| Abstract: | The pitting corrosion of the fresh stainless steel surface have been studied. The pitting critical potential of the fresh surface is lower than that of the surface covered by passive film. The pits on the fresh surface are primarily formed on grain boundaries and on inclusions. The morphology of pits are sharp streak pattern. According to the model of reaction steps of bare surface with chloride medium proposed by authors,the cours in which pits are formed on bare surface and the meaning of pit characteristic potentials have been discussed. |
