In order to obtain the self-lubrication and anti-wear metal surfaces and improve the service life and reliability of metal friction couples under condition of high contact stress, the composite coatings composed of Ni-base alloy, (W,Ti)C and graphite particles are prepared on the surface of No. 45 steel by plasma spraying process. The friction and wear properties of the coatings are investigated under the conditions of dry friction conditions at room temperature, and the worn surfaces of the composite coatings are analyzed by SEM and EDX. The results show that the friction coefficients of the composite coating are 35％ and 38％ lower than those of the Ni-base alloy coatings when it rubs againdt Si3N4 and GCr15, and the wear resistance of the former is 3 and 3.5 times
