Abstract

Kinetics of Fe(CN) :· /Fe(CN) :- redox reaction couple on oxidized
Ti, Ni and on Ti02 and NiO single crystals has been studied
by fast methods of polarization and current measurements. From
experimental values of the exchange-currents and transfer coefficients
a and ~. and knowing the reaction mechanism, the potential
distribution in the metal-oxide film - electrolyte system for Ti
has been evaluated. It has been shown, that the main difference
in properties of passive oxide films on Ni and Ti lies in the
character of potential distribution at the oxide-solution interface.
