AbstractNi-Cr-Co-W-Mo-B powder as a brazing filler was prepared by gas atomization, and its microstructure and melting characteristics were determined by XRD and DSC. The microstructure and composition analyses across the bonded interlayer were performed by SEM. The wettability between Ni-Cr-Co-W-Mo-B alloy and Ni-based superalloy substrate is good. The bond tensile strenghth at 1073 K and stress rupture at 1283 K/248 MPa are 1123 MPa and 43 h respectively. After transient liquid phase bonding and heat treatment, the microstructure and composition of the joint zone resemble those of the superalloy substrate, and the joint properties are almost identical to those of the superalloy substrate.
