摘 要:
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.
