【Abstract】 In this study, the author evaluated ten kinds of electrolytic solutions and chose the best one fittimg for the use of dental alloy Ni-Ci-Al-Ti. A further experiment was carried out in order to meke out the working parameters of this electrolytic solution under room temperature. The results demonstrated that the finest polish appeared when the current density was 0. 67-0. 89 A/cm2 and when the time of electrolysis was 3 minutes. Therefore, it was convinced that the ability of eletrolysis of this alloy was good enough for the clinical use.更多还原
