Abstract

The present invention discloses process and apparatus for preparing composite material with gradient reinforcing phase. The composite material is prepared through fixing reinforcing alloy blocks in the required positions of the foamed plastic model, vacuum vibrating molding, heating the alloy blocks to 100-1200 deg.c with one outside electromagnetic induction heater, pouring base metal liquid, which infiltrates into the gaps of alloy powder to form great thickness gradient alloy layer with special function in the required positions of the base metal. The process has only once heating, no oxidation of the reinforcing alloy material, and raised flowability and permeability of the metal liquid, and is suitable for thick casting with two phases of different materials in high combination strength and high quality.

Description

Technical field

[0001] The present invention belongs to the technical field of surface gradient composite materials, and mainly relates to a manufacturing process and equipment of a reinforced phase metal gradient composite material. Background technique

[0002] Gradient composite materials are based on the requirements of use, select two materials with different properties, and adopt various composite technologies to make the composition and structure of the middle part continuously change in a gradient without obvious internal interfaces, so that the material properties and functions are along the thickness A new type of composite material with a gradient change in direction. Its remarkable feature is that it overcomes the performance mismatch problem of the combination of the two materials, and makes the two sides of the material have different functions. The material is now widely used in aviation industry, aerospace industry, nuclear energy technology, electronics, optics, ...
