Abstract
This study attempted to polish pure titanium testpieces electrolytically to mirror surface at the size of cast denture frames.Electrolytic polishing of pure titanium could be done on an area of 30cm2 with a non-aqueous electrolyte.
Small pure titanium plates could be polished electrolytically, but a uniformly smooth surface could not be obtained easily with large testpiece.
The optimal electrolytic conditions were 30V for 6 min at 25℃ using a solution consisting of 70ml ethyl alcohol, 30ml iso-propyl alcohol, 6g aluminum chloride, and 25g zinc chloride,
The solution was safe and had less restriction of frequency of use.
