Abstract

The TiC coating was prepared on TC4 alloy using argon arc cladding method of graphene and titanium powder to improve wear resistance. The microstructure and phase of coating was observed by XRD, OM and SEM. The properties of coating were tested by microhardness-tester and dry slipping friction tester. The results show that the coating consists of TiC and Ti, and the composite coatings have good bonding with substrate. The in-situ synthesis of TiC particles are uniformly distributed in the composite coatings, and the morphology of TiC particles are composed of particle-shaped, rod-like and flower-like morphologies. The average microhardness of composite coating can reach 835 HV, about 2.8 times of the substrate. The composite coating has excellent tribological properties.
