| Abstract: | Brazed cBN wheel segments were fabricated based on graphite self-lubricating effect.Bending strength of the wheel segments were measured by three-point bending experiments.Bonding interface and fracture morphology of the wheel segments were detected using scanning electron microscope(SEM) and energy dispersion spectrometer(EDS).The results show that the bending strength of the wheel segments with mass fraction 5 % graphite reaches 116 MPa.The metallurgical bonding at the interfacial zone between cBN and Cu-... |
