摘要：Non-metallic inclusions are a leading cause of localized corrosion in steel, which frequently results in accidents, posing significant threats to safety. Opinions on the mechanism of localized corrosion induced by non-metallic inclusions vary, and currently, there is no effective method to prevent the occurrence of localized corrosion. Through rigorous systematic screening, we identified that Y2O3 inclusions can markedly reduce the localized corrosion associated with inclusions. These Y2O3 inclusions exhibit remarkable stability in corrosive environments, boasting superior corrosion resistance and machinability. This study provides a new theoretical foundation for the design of highly corrosion-resistant oil casing steel.
