Preparation of Brazed CBN Abrasive Tools Using Composite Fillers of AgCuTi Alloy and TiB₂ Particles

Abstract:

In order to dominate the wetting behavior of molten Ag-Cu-Ti alloy and control the brazing reaction at the joining interface, CBN abrasive grains were brazed using the composite filler of Ag-Cu-Ti alloy and 8 wt.% TiB2 particles. Ag-Cu-Ti alloy without reinforcing particles was also applied in the current investigation to compare with the composite filler. The characteristics of the joining interface and the reaction products were examined using optical microscope, scanning electron microscope, and X-ray diffraction instruments. Finally, the morphology of the CBN grains on the working surface of the brazed abrasive tools was observed. Results obtained show that the composite filler containing TiB2 particles distribute uniformly in the filler layer. Moreover, the interfacial chemical reaction of CBN grains and Ag-Cu-Ti alloy is restrained when TiB2 particles are added. The sharp edges of CBN grains are exposed fully due to the decreased wetting behavior of the composite filler.
