中文摘要：

立方的硼氮化物(CBN ) 的以铜锌金焊接的过程当 filler 材料被执行，有混合的 AgCuTi-TiC 的谷物和 AISI 1045 钢搽粉。加入的力量和界面的微观结构被调查。试验性的结果显示在 AISI 1045 钢上传播熔融的 filler 材料随 TiC 内容的增加被减少。一个好接口通过弄湿的行为在 TiC 微粒和 AgCuTi 合金之间被形成。在 AgCuTi+16wt% TiC 的情况中，以铜锌金焊接的 steel-to-steel 关节的力量在 filler 层以内在 TiC 粒子的加强效果之上到达了 95 MPa 依赖者的最高的价值。TiB2， TiB，和锡的以铜锌金焊接的 resultants 被 B， N，和 Ti 原子的 interdiffusion 的优点在 CBN 谷物和 AgCuTi-TiC filler 层的接口生产。

英文摘要：

The brazing process of cubic boron nitride （CBN） grains and AISI 1045 steel with AgCuTi-TiC mixed powder as a filler material was carried out.The joining strength and the interfacial microstructure were investigated.The experimental results indicate that the spreading of the molten filler material on AISI 1045 steel is decreased with the increase of TiC content.A good interface is formed between the TiC particulates and AgCuTi alloy through the wetting behavior.In the case of AgCuTi＋16wt% TiC,the strength of the brazed steel-to-steel joints reached the highest value of 95MPa dependent upon the reinforcement effect of TiC particles within the filler layer.Brazing resultants of TiB2,TiB,and TiN are produced at the interface of the CBN grains and the AgCuTi-TiC filler layer by virtue of the interdiffusion of B,N,and Ti atoms.
