Eight different dental amalgams were studied in an in vitro corrosion test. Cylindrical test specimens were stored in weak lactic acid solutions at different pH for 1 month. The concentrations of mercury and copper in the solutions were measured and corrosion depths estimated. The results indicated that more copper was released from non-gamma 2-amalgams compared with conventional ones. The amounts of copper from these amalgams were not directly correlated to the concentration in the alloys. Mercury was released in much lower amounts than copper for all amalgams and seemed to originate from the gamma 1-phase. A low pH promoted the corrosion.
在一项体外腐蚀试验中研究了八种不同的牙科汞合金。将圆柱形试样在不同pH值的稀乳酸溶液中储存1个月。测量溶液中汞和铜的浓度并估计腐蚀深度。结果表明，与传统汞合金相比，非γ2汞合金释放出更多的铜。这些汞合金中铜的含量与合金中的浓度没有直接关系。对于所有汞合金，汞的释放量远低于铜，并且似乎源自γ1相。低pH值会促进腐蚀。
