Electroless Co-Fe alloy deposition on the substrate of amorphous ribbon in a bath containing DMAB as a reducing agent was studied using an electrochemical polarization curve. The deposition rate was predicted by anodic and cathodic polarization curves for electrolessly-deposited Co-Fe alloy electrodes in the plating bath. The catalytic activity sequence of Co-Fe alloy electrode for anodic oxidation of DMAB was estimated from the current density-potential curve in an anodic partial bath not containing metal ions, and led to clarification of the relationship between the deposition rate of Co-Fe and the alloy composition of the deposit. The catalytic activity sequence of amorphous ribbon electrode depending on its alloy composition for anodic oxidation of DMAB was itself found to significantly affect the deposition rate in the initial stage.
