Resumen:
p style="text-align: justify; text-indent: 35.4pt;" class="MsoNormal">The electroreduction of silver
chromate films prepared by anodic polarization of polycrystalline silver in
solutions containing chromate was studied. The potentiodynamic
current-potential behavior as well as the potentiostatic current-time
dependence is adequately described by using the layer-pore resistance model. The
electroreduction of the Ag2CrO4 films occurs mainly under
ohmic control. The properties of the Ag2CrO4 films are
dependent on the formation conditions. A current contribution of reversible
kinetic characteristics attributed to the reduction of a gel-like structure is
also obtained.
