| Abstract: |
| The existence of H2S in environment is one of the factors causing discoloration of Cu. The inhibition of BTA, MBI, MBT, and the stability of BTA–Cu protection layer in H2S atmosphere were investigated. The experimental results were analyzed by quantum chemistry calculation method. Results indicated that BTA is a perfect corrosion inhibitor for Cu in H2S environment while the performance of MBT is discontented. |
