Sažetak
In this paper corrosion resistance of two experimental dental alloys, Co-Cr-Mo and Co-Cr-Ni, one commercial Co-Cr-Mo (Wironite) alloy, high purity titanium and Ag-amalgam (Permite) was studied in Ringers solution. On the basis of electrochemical measurements, the relevant indicator of local corrosion - pitting potential, at which the breakdown of passive layer and effects of local corrosion start, was determined. By ranking of materials according to pitting potential, it was found that pure titanium is the most stable material followed by commercial alloy Wironit, Co-Cr-Mo and Co-Cr-Ni alloys, while amalgam showed the lowest resistance in the experimental conditions of model oral cavity medium.
