| 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. |
