Title: EFFECT OF CATHODIC POLARIZATION ON CHEMICAL AND ELECTROCHEMICAL STATES INSIDE OCCLUDED CELLS OF LOCALIZED CORROSION OF A3 STEEL
Abstract:A simulated galavanstatic occluded cell was used to investigate the effects of cathodic protection on chemical and electrochemical states inside occluded cells of localized corrosion for A3 steel in 0...A simulated galavanstatic occluded cell was used to investigate the effects of cathodic protection on chemical and electrochemical states inside occluded cells of localized corrosion for A3 steel in 0.01 mol/L NaCl solution ( pH=10.00, t =50℃). It was found that Cl - concentration of the occluded solution decreased by electro\|migration, solution pH inside occluded cells increased from 5.6 to above 12, the surface of A3 steel can from passive film, the E corr of the occluded cell did rise, corrosion rate decreased, so the localized corrosion of A3 steel in the solution was retarded.Read More
