Specific embodiment
A kind of Cu-Ti3AlC2Composite material, using copper powder as matrix phase, with ceramic phase Ti3AlC2For reinforced phase, metal The percentage by volume of copper powder in the composite is 60%；The Cu-Ti3AlC2Composite material is by copper powder and Ti3AlC2 Powder presses processing step to be prepared again through first pressing-sintering-.
Preparation method, comprising the following steps:
(1) reduction of copper powder: copper powder is subjected to prereduction under reducing atmosphere, obtains copper reduction；
(2)Ti3AlC2The acquisition of powder: by Ti3AlC2The Ti that particulate abrasive is 5~10 μm to partial size3AlC2Powder；
(3) mixing: being 60% by copper reduction and Ti by copper powder percentage by volume in the composite3AlC2Powder End is uniformly mixed, and obtains mixing；
(4) powder is suppressed: the mixing of step (3) being added in steel mold, applies 300Mpa to steel mold on tablet press machine Pressure is pressed into idiosome；
(5) it is sintered: the idiosome of step (4) compacting being sintered in tube furnace, protective atmosphere is hydrogen, sintering temperature 820 DEG C, 1.5h is kept the temperature, is cooled to room temperature, obtains Cu-Ti3AlC2Composite material crude product；
