This study investigates the deposition of CoFe alloy films onto steel electrodes from aqueous acetate baths. The main objective was to evaluate the cathodic polarization, deposition efficiency, and film composition under varying current densities and bath compositions. A galvanostatic method was employed for the deposition, utilizing solutions of Co(CH3COO)2, FeSO4, and acetic acid. Results indicated that the deposition exhibited anomalous behavior, with iron preferentially deposited over cobalt, attributed to iron hydroxide surface precipitation. Higher current densities improved efficiency, while increased acetic acid concentration decreased it. Scanning Electron Microscopy (SEM) analysis of the deposits revealed smooth, dense, and uniform films, though microcracks were also present. This research contributes valuable insights into the electrodeposition parameters for CoFe alloys, confirming their potential application in industries where magnetic materials are critical, and highlighting the need for further exploration of their deposition conditions in comparison to more commonly studied NiFe alloys.
