Abstract 316 L stainless steel samples were passivated in NaClO containing solutions in order to simulate disinfection processes. Passive films were grown at the open circuit potential by immersion in NaClO aqueous solutions at different concentrations and temperature in order to understand how exposure to aggressive environments could affect subsequent corrosion resistance of SSs. In the attempt to study the passive film growth mechanism, in-situ Open Circuit Potential measurements were performed in the same growth solutions. Photoelectrochemical and impedance investigation of passive films was carried out in order to link their solid state properties with their corrosion behaviour.

NaClO 消毒/清洁对 AISI 316L 钝化膜的影响

摘要 316 L 不锈钢样品在含 NaClO 的溶液中钝化以模拟消毒过程。通过浸入不同浓度和温度的 NaClO 水溶液中，在开路电位下生长钝化膜，以了解暴露于腐蚀性环境如何影响 SS 的后续耐腐蚀性。为了研究钝化膜的生长机制，在相同的生长溶液中进行了原位开路电位测量。对钝化膜进行了光电化学和阻抗研究，以将它们的固态特性与其腐蚀行为联系起来。
