  • Title: [Electrochemical examinations of influence of mechanical treatment of surfaces on the corrosion of different dental amalgams. 1. Potential and corrosion rate and breakdown potential].
    Author: Weiland M, Werner H.
    Journal: Stomatol DDR; 1990 Mar; 40(3):103-5. PubMed ID: 2284650.
    Abstract:
    In a cell with artificial saliva the electrochemical behaviour of amalgam specimens of Germadent, Duragam and ANA 2000 is analysed in dependence of the surface treatments carving, burnishing and polishing using potentiodynamic polarization with low polarization rate. The less roughness and content of gamma-2-phase the better the amalgam reacts to corrosion evident in a higher potential, a lower corrosion rate and a higher breakdown potential. Foremost the polish supplies the best resistance to corrosion. Duragam-amalgam is more resistant than Germadent-amalgam. Polished specimens of Duragam react likely specimens of ANA 2000.
