A process for preparing an electroconductive metal coating on a substrate wherein precursor compounds capable of decomposing to form an electroconductive coating are subjected to localized high intensive heat, followed by rapid cooling, while maintaining the bulk of the substrate and/or the surrounding atmosphere at a lower temperature. The process is particularly suited for preparing valve metal substrates coated with mixed oxides comprising at least one metal belonging to the platinum group and a valve metal. Such can be utilized as dimensionally stable anodes in electrolytic processes. The process is moreover useful for applying oxides coating on metal and non-metal substrates of different kinds, such as ceramics, glass, plastics and polymeric organic supports. |
