Potentiokinetic polarization curves indicated that pitting potentials (Epit) decrease linearly with the log of chloride concentration. The rate of pit nucleation (1/ti), and the rate of pits growth increases with increasing concentration of Cl- ions. Initiation of pitting attack could be ascribed to the adsorption of Cl- ions on the oxide surface. Adsorption of Cl-ions is physisorption and follow the Langmuir isotherm with ?adsG0 = -21.1 kJ/molTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
