Issue Date: | 2007 | Journal: | Environmental Engineering and Management Journal | Abstract: | Electrochemical impedance spectroscopy (EIS) measurements were used to characterize the electrochemical behaviour of the some commercial dental alloys: two PdAg based alloys (Paliag, PaliagMaestro), two NiCr based alloys (Wirolloy, VeraSoft), two CoCr based alloys (Vitallium, VeraPDI) and two CuAl based alloys (Gaudent, NPG+2) in artificial saliva. Impedance spectra were represented in the form of Bode plots and it was fitted using a commercial softwere package called Electrochemistry Power Suite. The passivation of all the samples occurred spontaneously at the open circuit potential. The alloys Paliag, Wirolloy and Vitallium are in the optimum corrosion resistant condition. | URI: | http://hdl.handle.net/10553/72776 | ISSN: | 1582-9596 | Source: | Environmental Engineering and Management Journal [ISSN 1582-9596], v. 6 (4), p. 313-317 |
