Abstract
Purpose: The purpose of this study was to investigate to effect of the electro-polishing condition according to
electrolyte temperature and current and polishing time on surface morphology and composition by scanning electron microscopy(SEM) and energy dispersive X-ray spectrometer(EDS) in dental casting Co-Cr-Mo alloys.
Methods: 16 specimens were divided into 4 groups which have each 4 specimens. The size of specimens were 10 wide and 5 height. the electro-polishing of specimens are by polishing solution temperature and times in Co-Cr-Mo alloy by SEM and EDS analysis.
Results: The results shows that most smooth surface is obtained when electro-polishing is performed at 49 for
30-40sec with electro gap of 10mm and 8 voltage.
Conclusion: The morphologies of specimens after electro-polishing were scratch absent and significant between at 40 for 45sec and at 49 for 45sec.
