Abstract | Self-lubricating antiwear composite coatings were fabricated on Ti6Al4V alloy by laser cladding. The dry sliding wear tests under various temperatures (ambient temperature, 350°C and 700°C) and normal loads (3, 6, 9 and 12 N) were accomplished, and the corresponding wear mechanisms were investigated. Results show that the composite coating presented lower friction coefficient at ambient temperature and 700°C, and the wear rate increased monotonously from ambient temperature to 700°C. The reasons are that the hard phases of TiC and TiWC2 carbides enhance the wear capabilities at ambient temperature to 350°C. The CrS and Ti2CS sulphides have friction reducing effect at 700°C. The friction coefficient decreased and the wear rate increased with the increasing of normal load. It is ascribed to the effects of the CrS and Ti2CS sulphides at moderate normal load. It is implied that the tribological property of the composite coating showed the best at ambient temperature and moderate normal load. |
