brazing

1.The theoretical rules among the high temperature performance of the brazing alloy, strain rate and the function of Co alterant are analyzed.

析了钎料温性能与应速率、钴的质剂作等因素之间的理论规律。

2.Brazing quality and product reliability are both increased as using high frequency pulse microplasma arc heating process for assembly brazing of cathode and photoetching grid of electron tube.

采脉冲微束等离子弧做为电子管阴极和光刻栅极装配钎焊工艺的热源,提了钎缝质量和产品的可靠性.
