Abstract

The invention discloses a method for preparing a porous ceramic / metal bicontinuous phase composite material composed of an adjustable matrix phase and a reinforcing phase. The method comprises the following steps: by using one or more of metal powder and alloy powder as matrix powder, adding non-metal powder 1 promoting alloy generation or serving as an alloy component or perfecting a porous ceramic material and metal wettability, adding non-metal powder 2, and uniformly mixing to serve as filling powder; by using porous ceramic as the reinforcing phase, putting the porous ceramic in a container, pouring the filling powder in the porous ceramic, continuously rotating and vibrating or carrying out low pressure pressing to fully fill the powder in the porous ceramic pores, and pouring a proper amount of filling powder on the porous ceramic with fully filled filling powder; then, maintaining the temperature for a period under a protective atmosphere, and naturally cooling to the room temperature to obtain the porous ceramic / metal bicontinuous phase composite material composed of the adjustable matrix phase and the reinforcing phase.

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...
