Problems solved by technology

However, this process should also consider the properties of the interface products. For example, when two metals with different properties diffuse for a long time under heating, the interface is very easy to form brittle intermetallic compounds, which will affect the quality of the connection.
[0003] Diffusion connection generally achieves the purpose of connection through mutual diffusion of atoms under heating, but excessive temperature and uneven temperature during heating will cause poor quality of the connection

Abstract

The invention relates to a preparation device and a process for an ultra-high-strength composite material structural member, belonging to the technical field of a diffusion connection device and a process technology of ultra-high-strength composite materials under the assistance of an electric field, comprising a shaft and a material I and a material II respectively fixed and capable of The upper mold and the lower mold are opened and closed, the upper mold is fixedly connected to the upper base through the upper backing plate, and the lower mold is fixedly connected to the base through the lower backing plate; the upper and lower backing plates are provided with copper electrodes connected to the pulse power supply; One end is connected with the lower backing plate, and the other end is connected with the power device; the upper backing plate, the upper mould, the lower backing plate and the outer casing of the lower mould are provided with cooling water jackets. According to the principle of diffusion connection and the characteristics of electroplasticity, the invention improves its diffusion connection process; the device has simple structure, good insulation, stable and accurate forming, and at the same time, the cooling water jacket is used to balance the temperature and reduce the influence of temperature fluctuation on the material. The superior ultra-high-strength composite material is obtained, which improves the surface quality, mechanical properties and service life of the product.

Description

technical field [0001] The invention relates to a preparation device and a process for an ultra-high-strength composite material structural member, and belongs to the technical field of a diffusion connection device and a process for ultra-high-strength composite materials assisted by an electric field. Background technique [0002] The general diffusion connection is to make the surfaces to be diffused contact each other under a certain temperature and pressure, through microscopic plastic deformation or through the close contact of the two surfaces to achieve the gravitational range between the mutual atoms, forming metal parts, and achieving the effect of diffusion connection. Diffusion connections are generally divided into three stages: the stage of physical contact, the stage of activation of the contact surface, and the stage of formation of reliable joints. The above three stages are the main characteristics of the diffusion bonding process, and the process is carrie...
