Description
The paper presents a new method of metal-ceramic brazing that provides high-quality connections. A technology has been developed for tubular metal-ceramic connections, and a device has been created to create pressure on the connecting parts due to the difference in thermal expansion coefficients. The temperature deformation has been determined by calculation.
Despite the fact that various methods and technologies for the manufacture of metal-ceramic parts have been introduced in the industry, improvement and modification of these existing technologies are still necessary to make them more easily adaptable. In this regard, the selection of appropriate materials and joint design are critical factors in the development of technologies.
To solve the problem of joining tubular products made of ceramics and metals, a method for creating a uniform compressive stress over the entire surface was proposed, based on different coefficients of thermal linear expansion of metals during heating. To analyze the process described above, modeling was carried out based on the finite element method. The results of mathematical modeling can be used to judge the effectiveness of the method of creating compressive stresses between joints of complex-shaped materials. The results of the research are presented.
