中文摘要: 在NaCl-KCl-Na2WO4-CuO体系中采用熔盐电解法直接制取钨铜合金粉,并对产物进行了XRD、SEM及EDS分析。结果表明,在780~800 ℃电解、阴极电流密度106~133 mA/cm2、电解时间3~4 h、电压2.2~3.2 V的条件下,可以得到纯度99%以上、平均粒度0.91 μm的钨铜合金粉末,各项指标基本达到了工业上烧结钨铜合金的要求。
Abstract:Tungsten copper alloy powder was directly prepared in NaCl-KCl-Na2WO4-CuO system with molten salt electrolysis. The cathode electrolysis products were analyzed by XRD, SEM and EDS. The results show that copper tungsten alloy powder with purity of above 99% and average particle size of 0.91 μm is obtained under the reaction conditions including electrolytic temperature of 740~820 ℃, cathode current density of 106~133 mA/cm2, electrolysis time of 1.5~3.5 h, cell voltage of 2.2~3.2 V. The product reaches the manufacture requirement of sintering tungsten copper alloy in industry.
