Abstract Ceramic-reinforced high entropy alloy coating was prepared on the surface of stainless steel used in 0Cr13Ni5Mo turbines by laser cladding technology. Using microhardness and dilution rate as indexes, an orthogonal experiment with three factors and three levels were performed, and the optimal single-channel cladding technology was determined as follows: laser power 2 500 W, scanning speed 200 mm/min, powder feeding speed 9.5 g/min. AlCoCrFeNi-1wt% Ni-coated Al₂O₃ composite coating was prepared with the optimum process parameters and 50% bonding rate. The microstructure, phase and microhardness of the composite coating were analyzed and characterized by X-ray diffractometer, scanning electron microscope and microhardness tester. The influence of heat treatment at 850 ℃ for 2 h on the erosion resistance of the composite coating was studied by an injection-flow erosion test device. The results show that the microstructure of the composite coating does not undergo phase transformation after heat treatment, and the composite coating is still composed of single-phase solid solution with body-centered cubic structure (BCC), but the grain size is significantly refined. The microhardness of AlCoCrFeNi-1wt% Ni-coated Al₂O₃ composite coating increased from 504HV_0.3 before heat treatment to 545HV_0.3. Before and after heat treatment, the mass loss of the coating is 63.5 mg and 50.5 mg when the coating is eroded for 30 min. The mass loss was 178.5 mg and 146.9 mg after 120 min of erosion. The composite coating showed better erosion resistance after heat treatment. After annealing treatment, the surface morphology of the coating showed a ‘furrow’ dominated by the micro-cutting effect of liquid and solid two-phase flow at low erosion angle. With the increase of erosion angle, the coating surface gradually changes from a single ‘furrow’ morphology to a composite morphology of ‘furrow’ ‘lip piece’ and ‘pit’ under the synergic effect of micro-cutting and impact crushing.
