Abstract

The invention discloses a method for preparing a porous ceramic / metal bicontinuous phase composite material whose composition of a matrix phase and a reinforcing phase can be adjusted. The combination is matrix powder, plus non-metallic powder 1 to promote alloy formation or as an alloy component or to improve the wettability of porous ceramic materials and metals, and then add non-metallic powder 2, which is used as filling powder after mixing evenly; the porous ceramic As a reinforcing phase, put it into a container, and then pour the filling powder into the porous ceramic, through continuous rotation and vibration or low-pressure pressing, so that the pores of the porous ceramic are filled with the filling powder, and on the porous ceramic filled with the filling powder Pour in an appropriate amount of filling powder; then keep warm for a certain period of time under a protective atmosphere and then cool naturally to room temperature to obtain a porous ceramic / metal bicontinuous phase composite material with adjustable matrix phase and reinforcement phase composition.

Description

technical field [0001] The invention belongs to a preparation method of a composite material, in particular to a preparation method of a porous ceramic / metal double continuous phase composite material whose composition of a matrix phase and a reinforcement phase can be adjusted. Background technique [0002] Porous ceramic / metal composite material is a structural form of ceramic / metal composite material developed in the 1980s, that is, the ceramic phase is continuously distributed in a three-dimensional network in the composite material, and the metal phase is also in a three-dimensional network in the composite material. Continuously distributed, they present a unique network structure in space. Since the network ceramic skeleton is three-dimensionally continuous with the metal, each phase can exert its unique properties. Therefore, porous ceramic / metal dual continuous phase composites have high strength, high hardness, good wear resistance and thermal shock resistance, hi...
