Electrochemical Investigation on Electroless Fe-B Deposition

In this paper we investigate the effects of plating parameters such as the coupled aluminum, bath composition and bath temperature on Fe-B electroless deposition by electrochemical method. The results show that coupled aluminum induces the Fe-B elecrtroless deposition by shifting the potential negatively and decreasing the polarization resistance of anodic and/or cathodic reaction. The variations of the bath composition and temperature shift the mixed potential and change deposition rate of Fe-B electroless deposition. Due to the interactions between the two half reactions on the catalytic surface, the plating rate determined by electrochemical measurement in the complete bath is higher than that determined from the simulation half-reaction cells.
