High-temperature ceramic/metal riveting-glass sealing combination connection method
The invention provides a high-temperature ceramic/metal riveting-glass sealing combination connection method and relates to a connection method of high-temperature ceramic/metal. The connection method solves the technical problems of poor joint intensity and low usage temperature of a present connection method when a high-temperature ceramic/metal structural member has a large size. The method comprises steps: first, pretreatment of ceramic and metal is carried out; second, glass sealants and binders are mixed and stirred, and coating is carried out; third, assembling, nail placing and rivet application are carried out; fourth, the product is placed in an electric resistance furnace for thermal insulation. Glass systems with different ratios are selected as sealing materials according to different ceramic/metal and usage temperatures. The glass sealants can match ceramic and metal in the thermal expansion coefficients, and can keep certain viscosity during high temperature usage, and high-temperature high-reliability sealing connection of ceramic/metal connection members is achieved. The connection method is used for obtaining high-temperature ceramic/metal riveting-glass sealing combination high-reliability connection.
