Production of Nanosize Interference-colored Oxide Films on the Ti6Al4V Alloy Surface Using the Method of Electrochemical Oxydation in Succinate Eletrolytes

Abstract

The research data obtained for the specific features of the formation of thin interference-colored films on the Ti6Al4V alloy surface in succinic acid solutions have been given. A maximum film thickness for given conditions is defined by the voltage value independent of the electrolysis mode. The oxide film color is defined by the preset forming voltage value independent of the current density and the electrolyte concentration. The obtained data are explained by that the formation of oxide in galvanostatic mode occurs under the conditions of the availability of the constant potential gradient in the oxide film. An increase in the value of voltage applied to the cell will condition a proportional growth of a maximum thickness of the oxide film because it result in an increase of the amount of electricity passed through the cell and in an appropriate increase in the oxidized metal mass
