Abstract

The stability of electrochemically formed NiF2 film in 1.0 M perchloric acid containing monovalent fluorides namely, NH4F, HF, NaF, KF and LiF, is investigated using cyclic voltammetry, chronoampe- rometry, atomic absorption spectroscopy and scanning electron microscopy. In addition to direct dissolution of nickel and dissolution through the oxide layer, a new mode of dissolution of NiF2 film as NiFÿ 3 and NiF2ÿ 4 through complex formation is proposed. This process is significantly influenced by the alkali metal ¯uorides. On a comparative basis the stability of NiF2 decreases in the order NH4F > HF > KF > LiF.
