Abstract

Data on the surface structure of Cu-Ni containing oxide films formed on titanium under the effect of electric spark and arc discharges are considered at the scale of tens to hundreds nanometers. The surface sites of films around electric discharge channels are perforated with pores of diameters around 10 nm. Spheroids with diameters of tens to hundreds of nanometers, which chiefly elements contain involved in the electrolyte components including heightened amounts of copper and carbon, are distributed over the surface. Furthermore, agglomerates formed by planar particles with sizes of tens to hundreds of nanometers of irregular geometric shapes are also present on the surface. Elemental compositions of the film surface and planar agglomerates coincide. The particles are supposedly the products of the electric-discharge erosion of the film material.
