The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12–15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss measurements, and optical microscope, it is shown that corrosion occurs due to the metastable pitting. It is proposed that formed metal oxides corrosion product could catalyzed chemical decomposition of hypochlorite solution to oxygen, which provokes the positive shift of the corrosion potentials into the region of metastable pitting.

用于运输12-15％次氯酸盐溶液的316Ti不锈钢储罐的腐蚀

在含有12-15％的商业次氯酸钠溶液的溶液中研究了由316Ti不锈钢制成的运输罐材料的腐蚀情况。使用电化学技术，失重测量和光学显微镜，表明腐蚀是由于亚稳点蚀而发生的。提出形成的金属氧化物腐蚀产物可以催化次氯酸盐溶液化学分解为氧气，从而引起腐蚀电位向亚稳点蚀区域的正迁移。
