| Abstract: | The changes within occluded cell for 45CrNiMoV high strength steel in NaCl solu-tion were studied with a simulated occluded cell.As anodic currents passed the cell a series of changes took place,the most important changes were pH fall and Cl-migration. It was found that the pH fall was proportional to current density and the time of current flowing. Consequently,pH fall was a function of the quantity of passing electricity.The Cl-migration versus unit anode area was proportional to the time of current passing. |
