Аннотация

The structure and the properties of oxide films formed on titanium in the diphosphate based electrolytes by plasma electrolytic oxidation in the spark-discharge regime at application of inter-electrode voltage 100 to 130 V have been studied. A possibility to obtain oxide layers containing alloying elements by the modification of the composition of electrolytes has been stated. It was found that the chemical and phase composition as well as the topography, the microstructure and the grain size of the formed layers depend on the electrolyte composition, applied current density and inter-electrode voltage. The effect of the chemical composition of the formed mixed oxide films on the corrosion resistance and catalytic activity has been discussed.
