A STUDY OF DEVELOPMENTAL MECHANISM OF PITTING OF LOW ALLOY STEEL IN SEA WATER |
| |
| Abstract: | The changes of composition (H+ and Cl-) of anodic solution within a pit and their influence on the development of pitting of low alloy steel in the process of the oxygen concentration cell have been studied. The diagram of developmental mechanism for pitting was plotted. The pitting developmental mechanism and the control factors of low alloy steel in sea water were ellucidated. It was shown that the corrosion current of oxygen concentration cell was an important control factor for pitting of carbon steel and low alloy steel in sea water. |
