摘要：

High frequency induction brazing of TiC cermets to steel using Ag-54Cu-33Zn (wt-%) foil at 1073-1273 K for 30-300 s was investigated in the present paper. Both interfacial microstructure and mechanical properties of the brazed joints were studied. Microstructural analysis results show that the interface can be divided into three reaction layers and the formation products on the joint are Cu(SS) (where SS means solid solution), Ni3ZnC0.7 and Ag (SS). With increasing brazing parameters, the thickness of Cu (SS)+Ni3ZnC0.7 layers beside base metals increases. The relationship between processing parameters and shear strength of the joints indicates that the highest shear strength value 105 MPa can be achieved when the joint is brazed at 1123 K for 60 s.
