[Electrochemical examinations to the influence of mechanical treatment of surfaces on the corrosion on different dental amalgams. 2: Measurements of potentiodynamic polarization with high polarization rate].
In a cell with artificial saliva the electrochemical behaviour of amalgam specimens of Germadent, Duragam and ANA 2000 are characterized in dependence of different mechanical treatments of surfaces using cycling voltimetry. In the beginning the influence of roughness on the corrosion is evident, but increasing the influence of chemical composition dominant. Duragam-amalgam is most resistant to corrosion. The content of copper in Duragam has a better effect than the high content of copper in ANA 2000.
