Keywords： CBN

Joining experiments of CBN grains to AISI 1045 steel were conducted using Ag-Cu-Ti composite fillers containing TiX (X= B2 or N) particles at 920 ℃ for 5 min. The influences of TiB2 and TiN particles on the interfacial microstructure features between CBN and filler were investigated comparatively.The experimental results show that TiN particles are more effective than TiB2 ones to control the interfacial reaction and particularly the resultants. Thermodynamic analysis reveals that the varied interfacial reaction induced by the addition of TiB2 and TiN particles is mainly atttributed to the activity change of the B and Ti elements in the brazing reaction system.
