To enhance the wear resistance of laser-cladded Ni-WC coatings, recrystallization and stress-relief annealing treatments were applied. The effects different on friction performance coatings analyzed using XRD, SEM, a tester. results showed that refined grains transformed Ni4B3 phase, with lowest crack rate (10.1%) observed at 800 °C. Stress-relief effectively released residual stress, achieving (6.3%) 500 °C, while promoting transformation Cr7C3 phase improving coating stability. Furthermore, was more suitable for enhancing resistance, as treated °C exhibited lower coefficient (0.46) smallest volume (0.351 mm3). In contrast, effective in hardness, highest microhardness (936.54 HV1).
