摘要
在一特制的可施加电场的单管熔化炉内,借助DIGIDROP DGD-DS接触角测试仪研究了元素Cr和电场对Cu/W之间润湿性的影响。结果表明:元素Cr是Cu-W熔渗体系很好的助熔渗元素,在Cu中添加元素Cr可以显著减小Cu/W之间的接触角;外加电场也可以减小Cu/W之间的接触角,在实验的电场强度内,其减小的程度不及元素Cr明显。
A special furnace was designed and applied to produce an external electrical field up to 4 kV/cm and to study the wettability between copper and tungsten. The results showed that chromium can significantly reduce the wetting angle between copper and tungsten, so benefit to Cu-W infiltration system. The electrical field can also reduce the wetting angle, but not so stronger by comparing with chromium in the experimental electrical field range.
