Abstract Corrosion of two types of antibacterial Cu-bearing 316L stainless steel was investigated in a medium containing sulfate reducing bacteria (SRB) by various surface characterization and electrochemical measurements. The addition of Cu does not improve the resistance of 316L stainless steel to microbiologically influenced corrosion. The anticorrosion performance of 316L-Cu-A is better than 316L-Cu-B, which is believed to be associated with the addition of elements La and Ce, rather than Cu, in the steel. The Cu ions react with sulfides produced by SRB to produce copper sulfide on the steel surface, increasing corrosion of the Cu-bearing stainless steels.

硫酸盐还原菌存在下抗菌含铜 316L 不锈钢的腐蚀

摘要 通过各种表面表征和电化学测量，研究了两种含铜 316L 抗菌不锈钢在含有硫酸盐还原菌 (SRB) 的介质中的腐蚀情况。添加 Cu 不会提高 316L 不锈钢对微生物影响腐蚀的抵抗力。316L-Cu-A的防腐性能优于316L-Cu-B，这被认为与钢中添加元素La和Ce而不是Cu有关。Cu离子与SRB产生的硫化物反应，在钢表面产生硫化铜，增加含铜不锈钢的腐蚀。
