Microstructure evolution and mechanical properties of SiO2f/SiO2 composites joints brazed by bismuth glass
Source abstract
Abstract
Abstract To extend the application of the SiO2f/SiO2 composites, self-joining process is indispensable. Reliable self-joining of SiO2f/SiO2 composites was achieved by Bi2O3–B2O3–ZnO glass. With a low glass transition temperature, the onset temperature of residual stress is much lower than that of active brazing. In addition, bismuth glass exhibits a good wettability on the surface of SiO2f/SiO2 composites. When the joints were brazed at 750 °C/30 min, the average shear strength of the joints reached 21.2 MPa, reaching 77.8% of the shear strength of SiO2f/SiO2 composites. This technology can effectively fill the bank of self-joining of SiO2f/SiO2 composites.
