| Outline of Final Research Achievements |
The effects of interstitial nitrogen and interstitial carbon on the corrosion behavior of steels were investigated in this study. Interstitial nitrogen and interstitial carbon have been reported to successfully improve the corrosion resistance of austenitic stainless steels (steels with chromium). However, it has yet to be clarified whether the interstitial nitrogen and interstitial carbon improve the corrosion resistance of steels in general, such as steels without chromium. It was demonstrated that both interstitial nitrogen and interstitial carbon inhibit the dissolution current density and improve the corrosion resistance of steels without chromium. The mechanism of the corrosion inhibition by interstitial nitrogen and interstitial carbon was analyzed focusing on both the aqueous environment, by dissolution products, as well as the solid solution metal itself.
