| Abstract: | A series of polysilazane (PSZ)-based adhesives, which could be employed for high temperature environment in aerospace industry, were prepared to bind amorphous SiBON ceramics. It was found that the addition of dopants had a significant influence on the binding strength of samples, and physicochemical properties of adhesives were also closely correlated to their kinds and quantities. The fracture mechanism and phase transformation in joints were characterized. New phases including C3N4, Si3N4, SiC, BN, Si, ZrB2 and amorphous SiCN, were formed with the increase of treatment temperature, influencing the binding strengths of samples. The maximum binding strength of joints could reach 16 MPa after heating at 1100 °C in N2. The macroscopic and microscopic images of the fractured surface of joints and finite element analysis of the joint indicated that the failure of the joint occurred not only at the binding layer but also at the ceramic substrate. This work can serve as a guide for binding amorphous ceramic for high temperature environment. |
