Abstract

The influence of surface finishing procedures on the corrodibility of high-copper amalgams was measured. Anodic polarization curves were determined in Ringer's solution for amalgam samples made from a dispersion and a ternary alloy. Three types of finishes were compared: as carved, burnished, and polished. The polarization curves of the burnished and polished specimens were statistically similar (P greater than 0.05) at all potentials investigated. The carved samples exhibited higher corrosion currents at most of the potentials investigated.

摘要

测量了表面处理程序对高铜汞合金耐腐蚀性的影响。在林格氏溶液中测定了由一种分散体和一种三元合金制成的汞合金样品的阳极极化曲线。比较了三种表面处理类型：原样雕刻、打磨和抛光。在所有研究的电位下，打磨和抛光试样的极化曲线在统计学上相似（P大于0.05）。在大多数研究的电位下，雕刻样品表现出更高的腐蚀电流。
