Due to its high strength and excellent corrosion resistance, titanium alloys are rapidly being used in construction materials, bicycles, watches, and glasses. In order to adapt to this kind of use and increase its added value, experts are studying various dyeing methods of titanium alloys, such as atmospheric oxidation method, anodizing method, chemical oxidation method, etc. These methods require special corrosive liquids and are carried out by other processes Dyeing treatment. The electrical discharge machining process in water can be used to obtain various dyed surfaces while machining according to the machining conditions.
Water discharge machining process is to give the workpiece a rough cutting surface with an appropriate depth of cut and perform finishing. On the one hand, the surface layer is removed, and on the other hand, it is dyed at the same time. In the past, the dyeing process that required two processes can be reduced to one process. The principle of the process dyeing is that the exposed metal surface is discharged, and the oxide generated by the electrolysis has a dyeing effect. Since the number of oxides ultimately determines the color tone, by controlling the average processing voltage, not only can all the hue be formed, but also the color can be changed at any location.
