Electrochemical studies on corrosion of stainless steel electrodes II Chronopotentiometri studies of the stainless steel electrodes

ABSTRACT

Chronopotentiometric studies have been carried out in potassium chloride solutions of different concentrations and pH at various scan rates. From these measurements calculations of the thickness of the formed film and specific charge transfer are obtained. By the help of the scanning electron microscope and the X-ray probe, elemental analysis of selected areas of the electrodes in chloride had been followed. At pH 2 and 8 neither chloride nor potassium are detected, whereas at pH 4 only the chloride peak is observed
