Abstract The general corrosion behavior of AISI 316 stainless steel (316 SS) and pure titanium (pure Ti) in H2SO4 solutions containing fluoride (F−) and chloride (Cl−) ions was evaluated quantitatively using potentiodynamic polarization tests. The general corrosion resistance of these two materials to F− and Cl− is compared and explained by the proposed mechanisms based on XPS analyses. Furthermore, F− and Cl− are found to have synergistic effects on the general corrosion behavior of these two materials, which are attributed to the effects of F− and Cl− on the penetration of each other into the film.

氟化物和氯化物对AISI 316不锈钢和纯钛在H 2 SO 4 溶液中的综合腐蚀行为的协同作用

摘要 AISI 316 不锈钢 (316 SS) 和纯钛 (pure Ti) 在含有氟化物 (F-) 和氯化物 (Cl-) 离子的 H2SO4 溶液中的一般腐蚀行为使用动电位极化测试进行定量评估。这两种材料对 F- 和 Cl- 的一般耐腐蚀性通过基于 XPS 分析的建议机制进行比较和解释。此外，发现 F- 和 Cl- 对这两种材料的一般腐蚀行为具有协同作用，这归因于 F- 和 Cl- 对彼此渗透到膜中的影响。
