The invention relates to a titanium alloy surface solid in-situ composite friction-reducing and wear-resisting material. The titanium alloy surface solid in-situ composite friction-reducing and wear-resisting material is characterized by comprising, by mass, 60%-90% of antiwear agents and 10%-40% of antifriction agents. The antiwear agents are 10-80 nm oxide powder, namely, one or more of aluminum oxide, ferric oxide and titanium oxide. The antifriction agents are one or more of 50-500 nm graphite, molybdenum disulfide, tungsten disulfide and the like. The sliding contact surface of a titanium alloy component is filled with the powder after the powder is evenly stirred. The small-particle antiwear agent oxide is wrapped by the large-particle antifriction agents, a friction layer can be easily formed on the surface of the titanium alloy component in the sliding process in a compacting and sintering mode, and high rigidity and good bearing capacity are achieved. According to the antifriction agents, the friction coefficient is remarkably reduced, and friction noise is reduced. The titanium alloy surface solid in-situ composite friction-reducing and wear-resisting material is suitable for friction reduction and wear resistance of the surface of the titanium alloy component serving under the harsh sliding working condition.
