TiCoMoNb basic shaft tile lubricating self-regulating composite material and preparation method thereof

The invention relates to a TiCoMoNb basic shaft tile lubricating self-regulating composite material. The composite material comprises a basic material TiCoMoNb, a solid lubricating phase PdAgPtAuCuZnand a lubricating regulating agent AgCuCdSe-SiN; a preparation method is characterized in that a hot centrifugal spray drying device is adopted and used for preparing TiCoMoNb-PdAgPtAuCuZn spherical powder, and preparing AgCuCdSe-SiN spherical powder; laser additive manufacturing and subtractive manufacturing equipment is adopted and used for preparing a TiCoMoNb-PdAgPtAuCuZn self-lubricating composite material; and a vacuum-pressure infiltration method is adopted and used for filling a curved micro-pore structure with a regulating agent AgCuCdSe-SiN powder. The TiCoMoNb basic shaft tile lubricating self-regulating composite material has the advantages of being compact in structure, high in purity, short in preparation period, simple in operation, easy to control, regular in arrangement ofmicropore flow channels,
