Anomalous Codeposition of Fe‐Ni Alloys and Fe ‐ Ni ‐ SiO₂ Composites under Potentiostatic Conditions: Experimental Study and Mathematical Model

A mathematical model has been developed to describe the electrodeposition of Fe‐Ni alloys and composites under potentiostatic conditions. This model can be used to predict the polarization behavior, partial current densities, and alloy composition of each of the components as a function of the applied potential. samples were deposited on platinum rotating disk electrodes from sulfate electrolytes under potentiostatic conditions, and the results obtained were compared to the model. The model predictions were found to agree well with the experimental observations for the Fe‐Ni and systems.
