oxide film

The investigation data of the formation peculiarities of oxide films on the Ti6A14V alloy in tartaric acid solutions have been given. It is shown that the behavior of alloy forming dependences is conditioned by the anode current density. At  j_a < 0.5 A∙dm^-2 the continuous oxide film is not formed on the alloy surface and the preset value of the final voltage on the cell is not reached.

The influence of the electrolysis parameters on the process of VT6 titanium alloy oxidizing in oxalic acid solutions is presented. It is shown that the nature of cell voltage-time curves for the alloy samples depends on the current density used. The interference-colored oxide films are formed on the surface of the alloy at the anodic current density above 0.5 A∙dm^-2. The maximal thickness and the oxide film color are determined by the cell voltage and do not depend on other electrolysis parameters.
