The surface composition of RuO2+IrO2 mixed oxide layers (1-2 μm thick) deposited on titanium by thermal degradation of the corresponding chlorides in aqueous or isopropanol solutions has been investigated. A surface enrichment with Ir, more pronounced for the layers obtained from isopropanol, has always been found. Electrochemical data reflecting the surface properties of RuO2+IrO2 at the surface.
