Adopting Rapid Chemical Liquid Deposition（RCLD） to produce Cr/C composites. The precursor used in the experiment is liquid carbon source, and the remperature of deposition is between 850 - 1100℃, and its system pressure is 0.1MPa. Using the scanning electron microscope to watch the micmstructure of Cr/C composites;measuring the physical and mechanical properties of Cr/C material. The research results indicates that RCLD can produce Cr/C composites of execllent pmperites quickly. The density is 1. 786g/cm^3 ;flexural strength is 118.9MPa; compressive strength is 84.6MPa; this material possesses better wear resistance and electric conductivity.
