Corrosion behaviour, creep resistance, compressive and tensile strength and hardness of a newly developed silver-rich commercial amalgam were investigated in order to evaluate its performance, as compared with three high copper amalgams, namely; admixed, unicompositional and Pd-enriched. The results have shown that Ag-rich amalgam was superior in corrosion behaviour, compressive and tensile strength. Creep values were comparable to those of Pd-enriched amalgam, whereas hardness measurements of the latter were significantly higher. The results were analysed on a compositional and microstructural bases.
为了评估一种新开发的富银商用汞合金的性能，研究了其腐蚀行为、抗蠕变性、抗压和抗拉强度以及硬度，并与三种高铜汞合金（即混合型、单组分型和富钯型）进行了比较。结果表明，富银汞合金在腐蚀行为、抗压和抗拉强度方面表现更优。其蠕变值与富钯汞合金相当，而后者的硬度测量值明显更高。基于成分和微观结构对结果进行了分析。
