SURFACE AREA RELATIONSHIPS IN POLARIZATION AND CORROSION

THE POLARIZATION BEHAVIOR OF SURFACES CONTAINING REGIONS WHICH EXHIBIT DIFFERENT OVERVOLTAGE PARAMETERS FOR THE SAME REACTION ARE DESCRIBED. ALSO, THE EFFECT OF CATHODE AREA FRACTION ON CORROSION POTENTIAL AND CORROSION RATE IS CONSIDERED FOR A CORRODING SURFACE CONTROLLED BY ACTIVATION POLARIZATION. IT IS SHOWN THAT THE CORROSION POTENTIAL AND CORROSION RATE ARE MOST SENSITIVE TO AREA CHANGES WHEN THE SURFACE IS LARGELY CATHODE OR ANODE. THE CORROSION CURRENT REACHES A MAXIMUM WHEN THE SURFACE IS EQUALLY DIVIDED INTO ANODIC AND CATHODIC REGIONS. /AUTHOR/
