Metal-ceramic composite material and method for manufacturing metal-ceramic composite parts

Abstract

The invention discloses a metal-ceramic composite material and a method for manufacturing parts of the metal-ceramic composite material. The metal-ceramic composite material is composed of the following components according to the mass ratio: silicon carbide 76-92%, aluminum 3-22.5%, silicon 0.4% ‑0.8%, zinc 0.8‑1.5%, magnesium 0.1‑1.6%, rare earth 0.2‑1.5%. The metal-ceramic composite material provided by the invention has the advantages of low expansion coefficient, light weight and high heat dissipation rate; and through repeated mechanical performance tests, it is proved that the metal-ceramic composite material also has high strength, good wear resistance and corrosion resistance abrasion resistance. Applying the invention to electronic parts and components can meet the performance requirements of chip packaging, high-power electronic materials and heat dissipation protection materials, improve the heat dissipation performance of the chip, and at the same time make the chip and the base material have a good thermal expansion match, improve the resistance Thermal and cold cycle impact ability, prolong the service life of the device.
