Abstract
The purpose of this development is to polish titanium materials to mirror surface by electropolishing method. The method which had two processes was reported by the previous report. One is the electrolytic process by the combination of high and low voltage. The other is the oxide film removal process under the condition that electrolysis is stopped. However, the electrolyte used in previous method has flammability and contains deleterious substance. This time, high quality electropolishing of titanium was effected by using the safety electrolyte produced from ethylene glycol and sodium chloride(NaCl).
