| Abstract: |
| The main factors influencing the corrosion of low alloy steel by adding H2O2 into seawater was studied through potentiodynamic polarization curves, rotating disk electrode tests, and weight loss method. The results showed that the corrosion rate was the highest when H2O2 was 0.8 mol/L and the solution temperature was 70 ℃. The acceleration effect turned remarkably while the stirring rate was enlarged. However, the acceleration effect was remarkable only in 350 min after adding H2O2 into seawater. |
