Silicon carbide heating plate brazing furnace

Silicon carbide ceramic material has high strength, high temperature oxidation resistance is strong, good wear resistance, good thermal stability, small thermal expansion coefficient, thermal conductivity, high hardness, thermal shock and chemical corrosion resistance and other excellent features, in the car, machinery, chemical industry, environmental protection, space technology, electronic information, energy and other fields have increasingly widespread application, has become a lot of industrial performance of other material can not be replaced in the field of structural ceramics.

With the rapid development of modern national defense, nuclear energy and space technology, as well as automobile industry and ocean engineering, the requirements for materials such as rocket combustion chamber lining, aircraft turbine engine blade, nuclear reactor structural components, high-speed pneumatic bearing and mechanical seal parts are increasingly high, so it is urgent to develop various new high-performance structural materials. SiC ceramics have been widely used in the petrochemical industry as corrosion-resistant containers and pipes, in the mechanical industry as bearings, cutting tools, and mechanical seals, and in the aerospace and automotive industries as promising candidates for future gas turbine, rocket nozzle, and engine components.

Vacuum brazing is carried out in the absence of air, using a specialized furnace, and delivers significant advantages: extremely clean, flux-free braze joints of high integrity and superior strength. Improved temperature uniformity when heating in a vacuum, and lower residual stresses due to slow heating and cooling cycle, results in significantly improved thermal and mechanical properties of the material. Other benefits of vacuum brazing include heat treating or age hardening of the work piece as part of the metal-joining process, all in a single furnace cycle. Like conventional brazing, vacuum brazing is easily adapted to mass production.
