Abstract

The invention relates to manufacturing of a damping material, in particular to a method for preparing a TiNiCu shape memory alloy damping composite. A porous TiNiCu shape memory alloy is prepared, holes of the TiNiCu shape memory alloy are filled with metal Mg, and the TiNiCu shape memory alloy damping composite, namely, Mg / TiNiCu is prepared. The defects that in an existing porous TiNiCu shape memory alloy preparation method, the porosity, the aperture and the hole type are all hard to control; and an existing technology of introducing Mg into the porous alloy cannot be used for filling porous TiNiCu alloy with Mg, and the damping performance and other mechanical performance of an alloy product need to be improved are overcome.

Description

technical field

[0001] The technical solution of the invention relates to the manufacture of damping materials, in particular to the preparation method of TiNiCu shape memory alloy-based damping composite materials. Background technique

[0002] With the development of society, mechanical equipment tends to be high-speed, efficient and automated, and the problems of vibration, noise and fatigue fracture caused by it are becoming more and more prominent. Vibration and noise limit the improvement of mechanical equipment performance, seriously damage the stability and reliability of mechanical equipment operation, pollute the environment, and endanger people's physical and mental health. Therefore, reducing vibration and noise and improving the working environment of man-machines is a key issue that needs to be solved urgently . For this reason, people have researched and developed various methods and technical measures to solve vibration and noise problems in engineering, amo...
