The dependence of the electrodepoutron of Fe-NI-CO alloys on hydrodynanucs, current density and solution temperature usmg pulse and pulse reverse currents have been mvestigated Depostt compositions with pulse current (PC) were smular to those obtamed with drrect current (de) However, pulse reverse currents (PR) between 20 and 2OOHz at higher peak cathodic and anoda~ current den&es and lngher temperatures resulted m deposits Hrlth lower Fe and h@er NI content than wrath e&er dc or PC The appearance of deposits obtamed by PC and PR were supenor to those obtamed by de Deposits were smoother and bnghter at 55Β°C than at room temperature, and were smoother and more adherent at higher rotation rates Key words pulse current, pulse reverse. current

The growth kinetics of passive films on Fe, Fe-10 Ni, Fe10 Cr, Fe-10 Ni-10 Cr have been determin ed in pH 8.4 borate buffer solution at 25Β°C using ellipsometer and coulometric techniques. Films found on the alloys were progressively thinner as the alloy concentration was increased. The correlations
