含铟银汞合金是用液态的汞铟合金而不是纯汞研膳成的银汞合金,使用时汞蒸气非常少。本文对这种现象的机理进行了实验研究。 材料和方法 含铟10％(Wt)的液态汞铟合金、60％Ag-28％Sn-12％Cu的高铜合金粉按粉液比1.00∶0.82研磨7s,制成含铟银汞合金试件。用同种高铜合金粉和液态汞按同样的粉液比研磨14s(使两种银汞合金性能接近)。 Auger电子分光镜检查 用3kV氩离子轰击样本表面,除去表面污染物,直到碳的峰值消失。在10kV加速电压、16μA测试电流、10~(-7)Pa压强下,获得
Indium-containing amalgam is a silver-mercury alloy made from a liquid mercury-indium alloy rather than pure mercury, using very little mercury vapor. In this paper, the mechanism of this phenomenon has been experimentally studied. MATERIALS AND METHODS High-copper alloy powders containing 60% Ag-28% Sn-12% Cu and containing indium 10% (Wt) were ground for 7 seconds at a powder-liquid ratio of 1.00: 0.82 to prepare an alloy containing indium-amalgam Pieces. The same high-copper alloy powder and liquid mercury at the same powder ratio grinding 14s (the two silver-amalgam performance close). Auger Electron Spectroscopy Bombard the sample surface with 3 kV argon ions to remove surface contaminants until the peak carbon disappears. At 10kV accelerating voltage, 16μA test current, 10 ~ (-7) Pa pressure
