中文摘要:
      采用雾化法制备Ag-Sn(9.7-χ/10)-In(χ=0,0.5,1.0,1.5,2.0)合金粉末。Ag-Sn-In合金粉末在空气中进行内氧化。实验结果表明,χ=0.5的样品的氧化率始终低于χ=0的样品的,说明微量添加In未促进氧化率的提高,相反抑制了其氧化过程;χ=(1.0,1.5,2.0)的样品氧化率的变化奇异:在温度低于700时,它们的氧化率高于χ=0,当温度和保温时间达到一定参数时,χ=0的氧化率变得更好。这说明在低温氧化时,添加In(1.0≤χ≤2.0)有利于氧化进行,而高温长时间氧化时,添加添加剂In作用不大,甚至会降低氧化率。通过全面试验探究出各样品均能取得较优氧化率的合理氧化温度参数为750℃。

英文摘要:
      Ag-Sn(9.7-χ/10)-In(χ=0,0.5,1.0,1.5,2.0) alloy powders were prepared by atomization. Within the Ag-Sn-In alloy powders were oxidized in air. The experimental indicates show that the oxidation rate of the samples of χ = 0.5 was always lower than that of the samples of χ = 0, a little added In cannot promote the increase of oxidation rate, instead inhibits its oxidation. The oxidation rate of the samples of χ = (1.0,1.5,2.0) varies oddly. When the temperature is below 700℃, their oxidation rate is higher than the samples of χ = 0 obviously, while the oxidizing temperature and holding time reaches a certain parameters, the oxidation rate of samples of χ = 0 is better. It shows that when it is at low oxidizing temperature for short time, added In of χ = (1.0,1.5,2.0) is good for oxidation reaction, but at high temperature oxidation for a long time, the effect of the additive In is not big, even negative on the oxidation reaction. According to the comprehensive test, we explore and conclude that the reasonable oxidizing temperature which the various samples can obtain a better oxidation rate is at 750 ℃.
