| Abstract: | In this paper, the Fe-based alloy coatings were prepared by laser cladding through orthogonal testing of proceeding parameters. The surface quality, micro hardness and microstructure of each sample under orthogonal testing processing parameters were analyzed by judgment of synthesis fuzzy theory. Based the results of judgment of synthesis fuzz method analysis, the optimized parameter were gained: 3.3kW of laser power, 70 mm of space to focus, 6 mm/s of scanning speed, 5g/min of powder feeding flow. |
