摘要：

The corrosion currents of 17-4PH stainless steel in an NaCl solution at various contents of dissolved oxygen are obtained by the method of Tafel extrapolation. It is shown that the dependences of the corrosion current on the concentration of dissolved oxygen are significantly different on the passive and cathodically activated specimens; however, they are similar after preliminary cathodic activation and after the anodic activation with chloride ions.
