Abetract-The anodic passivation of iron was examined with respect to the degree of proton hydration as well as the acid structure. The investigation was based on the electrochemical tneasurements, XPS study and sulphur dioxide analysis. When acid concentration is low, the passivity of iron is a resu
The passivity and passivity breakdown of polycrystalline iron is investigated through electrochemical methods complemented with ellipsometry, by employing plain 0.04 M NaOH and saturated Ca(OH), solutions with the addition of chloride salt of concentrations up to 1 M. The comparative results indicat
Iron passivated chemically in chromate solutions over a range of pH was electrochemically reduced in phosphate-borate buffer solution of pH 8.5. According to the chronopotentiometry, the passive fllm became thinner as the pH diminished, which was in agreement with the ellipsometric result. The rest
With the apparatus described it was possible to measure under potentiostatic conditions at frequencies up to about 1 kHz spectral densities of current noise comparable to the thermal noise at resistances of the order M Ohm. The spectral densities of the current noise at passive iron microelectrodes
