Description

technical field [0001] The invention relates to a ceramic fast connection device and a using method thereof. Background technique [0002] Ceramic materials have the advantages of high hardness, high strength, good wear resistance, good corrosion resistance, and excellent high temperature performance, and are widely used in many fields such as aerospace, nuclear power, chemical industry, and energy. However, due to the high hardness of ceramic materials, it is difficult to process them into complex shapes, which severely limits their applications. By joining ceramics, these shortcomings can be overcome, and the realization of ceramic joining is a key enabling technology for the future large-scale application of ceramic materials. A lot of research has been done on the application and connection technology of ceramics at home and abroad. At present, the most important connection methods include adhesive bonding, brazing, air reaction brazing and diffusion welding. The adhes...
