摘要
采用模拟闭塞电池研究45CrNiMoV低合金高强钢在NaCl溶液中闭塞区内化学状态的变化.
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.
