To elevate the wear resistance of TC4 alloy, Co₃₀Cr₈W_1.6C₃Ni_1.4Si coating was fabricated on the surface by laser thermal spraying (LTS). The morphologies and phases of obtained coatings were analyzed by scanning electronic microscope (SEM) and X-ray diffraction (XRD), respectively. The friction and wear properties of the coatings in poly-alpha-olefin (PAO)+2.5wt% molybdenum dithiocarbamate (MoDTC) oil were investigated by wear tester. The results show that the laser thermal sprayed Co₃₀Cr₈W_1.6C₃Ni_1.4Si coatings are primarily composed of Ti, WC_1-x, CoO, Co₂Ti₄O and CoAl phases, and the metallurgical bonding forms at the coating interface. The average coefficient of friction (COF) of Co₃₀Cr₈W_1.6C₃Ni_1.4Si coatings fabricated at the laser power of 1000, 1200 and 1400 W is 0.151, 0.120, and 0.171 with corresponding wear rate of 1.17×10^-6, 1.33×10^-6 and 2.80×10^-6 mm³·N^-1·m^-1, respectively, which increases with the increase of laser power. The wear mechanism is abrasive wear, and the dendrite size is the dominant role of anti-wear.
