In a comparative corrosion test specimen were produced from eleven different amalgams using two different plugging pressures and were exposed to two different corrosive solutions. As was to be expected containing amalgams corroded the most. A more accurate differentiation between the individual non gamma 2 amalgams and the two different plugging pressures was only possible with the stronger corrosive solution. Therefore this solution seemed to be better suited for a standardized corrosion test according to DIN 13904, part 2. The greater plugging pressure inhibits corrosion especially in badly corroding amalgams. This seems to be due to the limited diffusion which is the result of a smaller pore size.
在一项对比腐蚀试验中，使用两种不同的充填压力由十一种不同的汞合金制作试样，并将其暴露于两种不同的腐蚀溶液中。正如预期的那样，含汞合金腐蚀最为严重。只有使用较强的腐蚀溶液才能更准确地区分各个非γ2汞合金以及两种不同的充填压力。因此，这种溶液似乎更适合按照DIN 13904第2部分进行标准化腐蚀试验。较大的充填压力能抑制腐蚀，尤其是在腐蚀严重的汞合金中。这似乎是由于孔径较小导致扩散受限的结果。
