COMPARATIVE EVALUATION OF THE CORROSION RESISTANCE OF SOME CO-CR ALLOYS USED IN METAL-CERAMIC TECHNOLOGY
Co-Cr alloys are still used in metal-ceramic technology on the large scale. The purpose of this study was to provide a comparative analysis of the corrosion resistance by the polarization resistance technique of two Co-Cr-based alloys (codified Co-Cr- P and Co-Cr-PW) produced by the same manufacture...

| description | Co-Cr alloys are still used in metal-ceramic technology on the large scale. The purpose of this study was to provide a comparative analysis of the corrosion resistance by the polarization resistance technique of two Co-Cr-based alloys (codified Co-Cr- P and Co-Cr-PW) produced by the same manufacturer, which have a minor variation in chemical composition. Corrosion tests were performed at a temperature of 37 ± 0.5° C in a bath with heating and recirculation, in artificial saliva (SA) Carter Brugirard at pH = 7.58. Both tested alloys showed an increased corrosion resistance when immersed in artificial saliva, proving a good corrosion resistance and therefore a good biocompatibility. The Co-Cr-P test showed superior electrochemical values and, implicitly, higher corrosion resistance. |
