Problems solved by technology

[0005] The above two inventions have solved the connection problem between ceramic matrix composite materials or between metals to a certain extent, but the operation is relatively complicated, the repeatability is poor, the speed is slow, and it cannot be used for mass production; and the preparation process of chemical vapor deposition method is accurate. The temperature is poor, a large amount of exhaust gas is produced, and the environment is polluted

Abstract

The invention provides a method for joining a ceramic matrix composite and a high-temperature assembly through 3D printing. The method is characterized by comprising the following steps of (1) calculating a joining position of a joining material, drawing a vertical view, storing the vertical view as an STL (Standard Template Library) file, and transmitting data to a laser melting and rapid molding system; (2) mixing joining material powder and an organic adhesive, placing the mixture into a powder cylinder, and introducing shielding gas; (3) fixing the joining material powder and the organic adhesive in a molding cylinder by using a clamp, connecting the joining material powder and the organic adhesive by using a core mould, spreading powder and preheating a working platform to rotate the core mould; (4) designing laser power, scanning speed, sintering temperature, scanning distance and the like, and sintering according to the designed section information; (5) continuing to spread powder, and beginning the next-round scanning and sintering; (6) continuously repeating the step (5), filling a gap between the joining material powder and the organic adhesive, and sintering at a high temperature; and (7) removing the core mould. The method is highly integrated in technology, short in machining period, free of moulds and capable of realizing mass production; and due to the adoption of the shielding gas, the powder is prevented from being oxidized.

Description

technical field [0001] The invention relates to a method for connecting ceramic matrix composite materials and high-temperature components, in particular to a 3D printing method for connecting ceramic matrix composite materials and high-temperature components. technical background [0002] Ceramic matrix composites are a type of composite material that is composited with ceramics and various fibers. The ceramic matrix has excellent properties such as high temperature resistance, high strength, high stiffness, relative light weight, and corrosion resistance, but its fatal weakness is its brittleness. , when the material is in a state of stress, it will produce cracks, or even break and cause the material to fail. After being combined with fibers, the performance is greatly improved, so it is widely used in rockets and other aerospace and military fields. However, the working conditions of many aviation products are extremely harsh, so higher requirements are placed on the per...
