Abstract: Wear-induced failure of GH4169 nickel-based superalloy components in aircraft transport, transfer, and suspendedflight operations constitutes a critical engineering challenge requiring urgent resolution. The advent of high-power lasers has facilitated the application of laser cladding technology in metal-ceramic composite coatings to enhance material wear resistance. However, limited research exists regarding laser cladding composite coatings, particularly concerning laser cladding parameters of composite coatings and the wear resistance characteristics and underlying mechanisms of composite coatings. Therefore, in the present study, GH4169/WC composite coating was deposited by laser cladding, and the process parameters were optimized by Taguchi-grey relational analysis. Furthermore, the dry slip wear behavior and its mechanism were systematically studied under vibration conditions simulating the operation of airborne equipment at ambient temperature. The main results demonstrate that the Taguchi-grey relation method effectively consolidates multi-response objectives into a singular grey relational grade (GRG), achieving the optimization of laser cladding process parameters. The optimized laser power, scanning speed and powder feeding rate are 650 W, 2 mm/s, and 4.7 g/min, respectively. Notably, the predicted GRG (0.669 7) exhibits excellent agreement with experimental results (0.672 9), the prediction error is only 0.5%. Compared with GH4169 substrate, the composite coating reduces the wear depth by 38.2% and mass loss by 41.5%. In addition, with the increase in contact stress, the wear depth and wear amount of the material increases. And with the increase in sli-ding speed, the oxidation wear degree of the material gradually increases. The present study validated the efficacy of Taguchi-grey relation method in laser cladding optimization and elucidated the wear resistance mechanisms in metal-ceramic composite coatings, thereby providing theoretical foundations and experimental basis for enhancing the wear resistance of aerospace components.
