Спектры импеданса оксидированого алюминия, электрохимически модифицированного наночастицами никеля

Abstract

Samples of oxidized alumina, which had been previously modified under both anodic and cathodic polarization, were investigated with an impedance spectroscopy method. Corresponding equivalent schemes have been calculated by computer simulation, the field, which are related to surface morphology and space charge, have been identified. It was shown that the sample modified under anodic polarization are more stable against corrosion comparing with those, which had been activated under cathodic polarization.
