Abstract	Laser clad NiCr/Cr₃C₂ coating and Ti₂SC/CrS self-lubricating anti-wear composite coating using NiCr/Cr₃C₂–WS₂ powders were fabricated on Ti6Al4V substrates. Effects of annealing on microstructure, microhardness and tribological properties of the Ti₂SC/CrS composite coatings had been investigated systematically. Results indicated that the annealing process did not have significant effects on the phase constituents and microhardness. Compared with NiCr/Cr₃C₂ coating, the Ti₂SC/CrS coating shows good anti-wear and friction-reducing properties owing to the existence of in situ synthesized self-lubricating phases Ti₂SC and CrS. Furthermore, after the appropriate annealing process (at 600 °C for 1 h), the anti-wear property of the Ti₂SC/CrS coating could be significantly enhanced and is beneficial to the running-in surface of the counter-body.
