Coloring Method for Titanium Alloy by Using EDM Process.

A study to achieve a fine surface finish in Wire-EDM

“…By analogy, the ac pulse generator is employed, and it is confirmed by experiments that a fine surface can be achieved [2][3][4]6,7]. This result is readily understood because the oxidation of work material due to electrolysis when dc pulse generator is applied is suppressed [8].…”

Micro‐Electro Discharge Machining (µEDM)

“…[70] fabricated a microstructure shown in Fig. [71] developed a new method of coloring titanium alloys, using the WEDM process. The suitable discharge conditions for this process were predicted from the transient temperature analysis of the tool electrode and the workpiece.…”
