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.
在含有人工唾液的细胞中，使用低极化速率的动电位极化法，根据雕刻、打磨和抛光等表面处理方式，分析了Germadent、Duragam和ANA 2000汞合金标本的电化学行为。γ-2相的粗糙度和含量越低，汞合金的耐腐蚀性越好，表现为更高的电位、更低的腐蚀速率和更高的击穿电位。最重要的是，抛光提供了最佳的耐腐蚀性。Duragam汞合金比Germadent汞合金更耐腐蚀。Duragam的抛光标本与ANA 2000的标本反应相似。
