The effect of different electrolytes on the results from potentiodynamic polarization corrosion testing was studied for nine different dental alloys. In general, the difference in the results was greater between certain alloys using the same electrolyte than between the electrolytes with the same alloy. However, there were some differences between the electrolytes, most pronounced when testing dental amalgams. The electrolyte consisting of 1% NaCl seemed to offer the most corrosive environment. Darvell's and Fusayama's solutions were much less corrosive, at least for dental amalgam specimens. With regard to the ranking by corrosion sensitivity of the amalgams, only the results obtained by using Fusayama's solution were consistent with the clinical experience of the materials.
研究了九种不同牙科合金在不同电解质中进行动电位极化腐蚀测试的结果。总体而言，使用相同电解质的某些合金之间的结果差异大于相同合金在不同电解质之间的差异。然而，电解质之间存在一些差异，在测试牙科汞合金时最为明显。由1%氯化钠组成的电解质似乎提供了最具腐蚀性的环境。达维尔溶液和船山溶液的腐蚀性要小得多，至少对于牙科汞合金标本来说是这样。关于汞合金腐蚀敏感性的排名，只有使用船山溶液获得的结果与这些材料的临床经验一致。
