Abstract: A new integrated filler metal/base metal manufacturing method by cold spray additive manufacturing is proposed. The integrated CuTi filler metal/GH3536 and CuTi + W composite filler metal/GH3536 are prepared by cold spray additive manufacturing techniques. The large plastic deformation of Cu and Ti particles and the tamping effect of W particles promote the interfacial bonding of particles, which improves the weldability of cold sprayed CuTi + W composite filler metals. Based on the cold sprayed CuTi + W composite filler metal, the C f /SiC composites and GH3536 are successfully brazed, and the typical microstructure and brazing mechanism are investigated. As a result, the shear strength of C f /SiC-GH3536 joint brazed by cold sprayed CuTi + W composite filler metal reaches 77 MPa. This study highlightes the great potential of cold spray additive manufacturing for integrated filler metal/base metal manufacturing in brazing.
