摘要：
The paper presents the influence of chemical nature on the corrosion of dental alloys in Fusayama - Meyer artificial saliva with fluoride ions content, at human body temperature (37 degrees C). From evolution of open-circuit potential/time and polarization curves, as well as by processing Nyquist and Bode impedance plots, it was concluded that the biocompatibility of dental alloys depends mainly on the occurence of passivating film. Better electrochemical parameters were obtained for greater Cr content in the non-noble alloy, By adding of fluoride ions, the passive film was also developed, whereas the corrosion resistance is diminished.
