摘要
Through refining five types of pipeline steel with different Cu contents (0Cu, 0.6Cu, 1.0Cu, 1.3Cu, 2.0Cu, w%), the effects of Cu content and aging treat ment on the corrosion behavior of X80 steel in a Bacillus licheniformis environment were investigated from the perspectives of antibacterial performance, corrosion product analysis, and electrochemical behavior. The study revealed that only the 2.0Cu steel exhibited a notable antibacterial effect against Bacillus licheniformis. For rolled materials, the addition of Cu enhances corrosion resistance, but aging accelerates corrosion in Cu-containing steels. In bacterial systems, the corrosion current density of the material is lower compared to sterile systems, indicating that the microbial film offers some protective effect.
