Abstract: This work develops a Colmonoy 88 alloy reinforced with 50 wt.% tungsten carbide (WC) coating on ASTM A213 Grade T22 steel using laser cladding to address severe air-jet erosion encountered in boiler and high velocity particle environments. The coating formed a dense, metallurgically bonded layer with an average thickness of 562 µm and a hardness of 1054 ± 18 HV. Air-jet erosion behavior was evaluated using a central composite design with varying velocities, particle sizes, and impingement angles. Analysis of variance confirmed that all three parameters significantly influenced erosion mass loss (p < 0.0001). The clad surface exhibited around 70% lower erosion compared with the uncoated T22 substrate. Desirability-based optimization identified 37.39 m/s, 235 µm, and 48.77° as the minimum erosion condition. SEM fractography showed ductile ploughing in the T22 and brittle micro-chipping in the coating, indicating a shift in erosion mechanism due to the reinforced microstructure. The study integrates Colmonoy 88 + WC cladding with RSM-based optimization and mechanistic erosion analysis to enhance particle erosion resistance in power-plant components. Its novelty lies in combining laser-clad Colmonoy 88 + 50 wt.% WC on T22 steel with an RSM-driven erosion evaluation and optimization framework. [ABSTRACT FROM AUTHOR]
