| 摘 要： | 采用Ni-Cr、Ag-Cu-Ti和Ti-Zr-Ni-Cu等钎料分别对单晶金刚石与基体进行真空钎焊。SEM、EDS和XRD等分析结果表明,在一定的钎焊温度、时间及真空度下,金刚石与所有钎料均形成化学冶金结合,在不同钎料界面形成的碳化物的种类、数量和形貌分布却显著不同;Ni-Cr合金钎料在界面处形成片状的Cr3C2和针状Cr7C3;Ag-Cu-Ti钎料则生成不连续分布块状TiC,Ti-Zr-Ni-Cu生成的是呈鹅卵石状连续分布的TiC。

| Abstract: | Using Ni-Cr, Ag-Cu-Ti, and Ti-Zr-Ni-Cu alloy as fillers diamond was brazed on matrix in vacuum furnace. By SEM, EDX and XRD analysis, it is shown that at certain brazing temperature, duration and vacuum level, chemical bonding takes place on the interface between the diamond and all the fillers. The kind, amount, morphology and distribution of carbides formed are different on different filler interface. Some slice-like Cr3C2 and acicular Cr7C3 carbides exist on the interface of Ni-Cr, discontinuous-lump-like TiC carbide exists on the interface of Ag-Cu-Ti, and continuous-cobble-like TiC exists on the interface of Ti-Zr-Ni-Cu. |
