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).

This work aims to provide a comprehensive understanding of the structural impact micro-texture on properties bearing capacity and friction coefficient through numerical simulation theoretical calculation. Compared traditional optimization method single-factor analysis (SFA) orthogonal experiment, multivariate linear regression (MLA) algorithm can optimize structure parameters within wider range analyze coupling effect parameters. Therefore, in this work, micro-textures with varying texture size, area ratio, depth, geometry were designed, their was investigated using SFA MLA algorithms. Both methods obtained optimal structures, compared. It found that further improve based results. The 0.070409 be size 500 µm, an ratio 40%, depth 5 slit, having 10.7% reduction compared texture-free surface. In comparison, reduced 0.067844 by under 600 50%, 9 slit. final surface shows 15.6% surfaces 4.9% SFA.
