中文摘要：

wettability 和 C-C 上的四种基于 PdNi 的以铜锌金焊接 fillers 的界面的反应合成与无柄的落下方法被学习。结果证明这些以铜锌金焊接的 fillers 的 wettability 随 Cr 内容的增加被改进。Cr 在以铜锌金焊接的接口散布了合成的 filler/C-C， Cr23C6 阶段的形成被推测。在在以铜锌金焊接的 Ni-33Cr-24Pd-4Si 之间的接口 filler 和 C-C 合成，元素 Cr 与 C-C 反应了形成 Cr-C 反应层。和 Si 的 Pd 参予了界面的反应并且形成了 Pd2Si 和 Pd3Si 阶段。而且在这个反应地区，以铜锌金焊接的剩余合金变得 Ni 富有、弄空 Pd。

英文摘要：

The wettability and interfacial reactions of four kinds of PdNi-based brazing fillers on C-C composite were studied with the sessile drop method.The results showed that the wettability of these brazing fillers was improved with the increase of Cr content. Cr distributed at the interface of brazing filler/C-C composite and the formation of Cr23C6 phase was speculated.In the interface between Ni-33Cr-24Pd-4Si brazing filler and C-C composite,element Cr reacted with C-C to form Cr-C reaction layer.Pd together with Si participated in the interfacial reactions and formed Pd2Si and Pd3Si phases.Furthermore,in this reaction zone,the residual brazing alloy became Ni-rich and Pd-depleted.
