To enhance the hardness and wear resistance performance of Ti6Al4V alloy (TA), ZrO2–8%Y2O3 (8YSZ) coatings with NiCoCrAl as bond coat (BC) were fabricated on TA by laser direct energy deposition (LDED). The morphologies, chemical elements, phases and hardness of obtained coatings were systematically analyzed, and the effects of laser power on the friction–wear performances of 8YSZ coatings were investigated using a high temperature wear tester, and the wear mechanism was also discussed in detail. The results show that the dendrite structures of 8YSZ coatings become small and the eutectic areas decrease with the increase of laser power, and the coating hardness is 933–1078 HV0.5 higher than the TA. The average coefficients of friction (COFs) of 8YSZ coatings decrease with the increase of laser power, which are attributed to the enhancement of coating hardness. The wear rates of 8YSZ coatings deposited at the laser power of 1200, 1500 and 1800 W are reduced by 92.58%–98.52% compared with the TA, and the wear mechanism is dominated by abrasive wear, accompanying with tiny adhesive wear.
