Diffusion welding piece of high-purity zirconium oxide composite ceramic and red copper and production method of diffusion welding piece

Abstract

The invention provides a diffusion welding piece of high-purity zirconium oxide composite ceramic and red copper and a production method of the diffusion welding piece. By the adoption of a zirconium oxide composite ceramic plate, the ceramic surface is processed through a surface grinding method, then a metal zirconium coating is formed on the surface of the ceramic plate through a vacuum ion plating method, the red copper is in contact with the zirconium oxide composite ceramic plate through the metal zirconium coating, the entirety is put into a hot isostatic pressure sheath, degassing treatment is conducted, finally, the zirconium oxide composite ceramic plate and the red copper are welded through a hot isostatic pressure diffusion welding method, and the diffusion welding piece of the high-purity zirconium oxide composite ceramic and the red copper is obtained. The diffusion welding piece has the advantage that the welding interface strength is high. The technique and equipment are simple, cost is low, energy consumption is low, the production efficiency is high, the production method is suitable for industrial production, and a welding structure, which is stable in quality and high in bonding strength, of the zirconium oxide composite ceramic and the red copper can be obtained.

Description

technical field [0001] The invention belongs to the technical field of material preparation technology, and in particular relates to a diffusion welded piece of high-purity zirconia composite ceramics and red copper and a production method thereof. Background technique [0002] Diffusion welding means that under a certain temperature and pressure, the surfaces to be welded are close to each other and in contact with each other, and the physical contact of the connected surfaces is enlarged by causing local microscopic plastic deformation, or through the transient liquid phase generated by the connected surfaces, and then After a long period of interdiffusion and interpenetration between atoms, the connection process of metallurgical bonding is formed. The diffusion welding process can be roughly divided into three stages. The first stage is physical contact. Under the action of pressure and temperature, the microscopic protrusions on the rough surface first achieve plastic d...
