Problems solved by technology

[0006] As early as the late 1990s, Zhu Chuncheng of Harbin Institute of Technology and others reported the preparation of TiB2-TiC / Cu-Ni by using metal titanium, boron carbide, metal copper powder and nickel powder as raw materials through pressurized self-propagating high-temperature synthesis technology. Ablation-resistant materials, but due to the low bonding strength of the ceramic phase grains in the prepared composite materials, the thermal shock resistance of the composite materials is low, and there are no reports of subsequent applications

Abstract

The invention provides a layered ceramic titanium silicon carbide based on MAX phase (Ti 3 SiC 2 ) and metal copper composite material, comprising the following steps: (1) mixing: mixing titanium silicon carbide powder and resin powder in a ball mill and drying to obtain mixed powder. (2) Warm pressing molding: the mixed powder is placed in a mold, heated and pressed to form a green body. (3) Pyrolysis: The green body is pyrolyzed in a nitrogen environment to obtain a mixed skeleton of porous carbon and ceramics. (4) Reaction sintering to obtain porous ceramics. (5) Vacuum infiltration: Melt and impregnate porous ceramics with copper under vacuum to obtain metal / ceramic composite materials. The prepared composite material has a continuous three-dimensional network structure in which ceramics and metals interweave, exhibits good mechanical properties, and also has good electrical properties and wear resistance, and has a simple preparation method and has broad application prospects.
