Joining of SiC ceramics using high-silicon aluminum alloy fillers assisted by laser cladding

Journal of Materials Research and Technology, 2023
A Si–40Al joining transition layer was prepared via laser cladding, followed by brazing of SiC ceramics using Si–60Al alloy as the joint filler. The microstructure, composition, and flexural strength of the brazed joints were investigated under different
