Abstract

The invention discloses a titanium alloy diffusion bonding method assisted by ultrasonic impact surface modification, which involves ultrasonic impacting the surface of a titanium alloy plate, and then heating and diffusing the titanium alloy plate, so that the joints can be tightly bonded and the high-strength connection of the titanium alloy itself is realized. The invention adopts the method for obtaining the crystal grain refinement layer through ultrasonic shock surface modification, increases the atomic diffusion rate and reduces the titanium alloy diffusion connection parameters, and realizes the low temperature diffusion connection of the titanium alloy. The method is easy to operate, has good adaptability, high repeatability, is green and energy-saving, and can greatly improve industrial production efficiency.

Description

technical field

[0001] The invention relates to a diffusion bonding technology, more specifically, by ultrasonically impacting the diffusion bonding surface of a metal substrate, a grain refinement layer is formed in a certain depth region of the metal surface, so as to reduce the diffusion bonding temperature and improve the diffusion bonding performance Methods. Background technique

[0002] Titanium alloy is a metal structural material with high strength, low elastic modulus, high specific strength and good wear resistance, which is widely used in aerospace, automobile manufacturing, biomedicine and other advanced fields. However, the preparation of some complex and large titanium alloy components involves joining technology, and complex, precise, and strong welded joints with the base metal can be obtained through diffusion joining, which is suitable for various applications.

[0003] The microstructure and properties of titanium alloy joints are highly sensitive to dif...
