Pt-containing oxide layers on titanium and aluminum

Inorganic Materials Aims and scope

Abstract

Pt-containing films have been grown by exposing Al and Ti substrates to spark discharges in aqueous electrolytes containing Na6P6O18 and H2PtCl6. The average platinum content in the bulk of the films on aluminum and titanium is within 0.08 and 0.5 at %, respectively. The platinum is concentrated on the surface and in the near-surface region of the films, in the state Pt0 in the films on aluminum, Pt2+ on the surface of the films on titanium, and Pt2+ and Pt0 in the near-surface region of the latter films. The surface layer of the films contains arrays of dispersed platinum-enriched particles ∼1 μm in size.
