Abstract

The invention provides a method for implementing controllable gap connection of hard materials in atmospheric environment by heating and cooling with mould and a mould applied in the method. The hard materials to be connected include ceramic, glass and other hard materials. The method based on the existing mechanical vibration connection methods, such as ultrasonic-assisted connection, is characterized in that a special clamping mould is used, overall heating and cooling with mould is applied, and the method is organically used with high frequency vibration assisted connection to allow for reliable connection of hard materials in atmospheric environment. Using the special clamping mould has the advantages that connecting process devices are simplified, operation is simple; the materials to be connected are clamped to ensure stability of overall structure; gap between joint surfaces is controlled; sufficient pre-pressure is provided; the clamping mould serves as an indirect heating source to input sufficient heat for joints; cooling rate is retarded; separation of the connected workpieces is simplified.

Description

technical field [0001] The present invention relates to a method for connecting hard materials with controllable gaps through mold heating and cooling in an atmospheric environment and a mold used in the method, in particular to a fast, Efficient and strong connection method. Background technique [0002] With the advancement of science and technology and the development of social production, hard materials such as ceramics (oxide ceramics, nitride ceramics, boride ceramics, carbide ceramics, etc.), glass (oxide glass and non-oxide glass) and metal compounds or minerals Such materials have been widely used because of their excellent properties. Ceramics are widely used in materials engineering, electronic engineering, chemical engineering and mechanical engineering because of their excellent performance in terms of electrical properties, chemical properties, optical properties and heat resistance, which metals and other polymer materials cannot do. Especially in aerospace,...
