Research on PdNb Alloy Brazing Material Used for Cathode Welding of Vacuum Electron Devices
Pages: 130-131,135
Year: Issue:  19
Journal: Hot Working Technology

Keyword:  钯铌合金钎料焊接性阴极;
Abstract: 对PdNb二元高温合金焊料进行了熔化温度的测量及焊接工艺性能试验,对其阴极焊接件在1000~1200℃的真空条件下的蒸发进行了测试.结果表明:该焊料能满足真空电子器件阴极的焊接温度要求;在母材W、Mo上的润湿、铺展性能非常好,能完全润湿母材,铺展面积是放置焊料面积的10~15倍,润湿角接近0°;阴极W/Mo焊接件在1000~1200℃的真空条件下蒸发很少,满足了生产工艺要求.
