A home-made Electrochemical Scanning Tunneling Microscope/Scanning Tunneling Microscope (ESTM/STM) has been used for investigations of the anodic oxidation of polycrystalline nickel, being controlled by cyclic voltammetry and coulometry. A surface fragment with a(+/-)10% accuracy at the scale of 4800 nm x 4800 nm and 100 nm x 100 nm was observed. The best compact and relatively smooth layers of nickel oxides have been obtained in a concentrated (c=10.0 mol dm(-3)) sulphuric acid solution. In a diluted electrolyte (c=0.1 mol dm(-3)), the formation of the NiO-x islands is possible.
