To investigate the effect of recasting on the electrochemical corrosion of cobalt-chromium ceramic alloys,according to ISO 10271-2011,the cobalt-chromium ceramic alloys which have been cast and recast for 1~3 times under the circumstance of vacuum compressive casting with argon were studied by potentiodynamic polarization in artificial saliva(t=37.0 ℃,pH=7.4).The results showed that there presented no statistical difference in the electrochemical corrosion among three generations of cobalt-chromium ceramic ...
