Preparation method of carbon-ceramic wear-resistant composite material
The invention discloses a carbon-ceramic wear-resistant composite material and a preparation method thereof. According to the invention, a Ti-Cu binary alloy is used as an impregnant, carbon fibers are used as a reinforcement phase, and the C/C-TiC-Cu composite material with good structure and performance is prepared at low temperature through a reactive infiltration method. The phase composition of the composite material is TiCu (wherein x and y represent the atomic ratio of the alloy), TiC, C and a small amount of Cu phase. The preparation method comprises the following steps: (1) preparation and pretreatment of a C/C porous body; (2) preparation of an interface protection coating on the carbon fiber surface of the C/C porous body; (3) densification of the C/C porous body with the interface protection coating to obtain a porous C/C prefabricated body; (4) preparation of a Ti-Cu binary alloy; and (5) high-temperature infiltration treatment of the Ti-Cu binary alloy and the porous C/C prefabricated body so as to obtain the C/C-TiC-Cu composite material. The preparation method is simple in process and high in efficiency, the addition of the TiC ceramic phase improves the overall friction and wear performance of the composite material, and the introduction of the TiCu alloy phase can effectively regulate and control the friction and wear performance of the composite material.
