摘要
利用激光熔覆技术对铁基Fe90合金进行工艺参数的优化试验,运用模糊综合评判理论对正交试验参数下各试样的表面质量、硬度和显微组织进行分析和综合评价,找到了优化后的最佳工艺参数:激光功率3.3kW、离焦量70mm、扫描速度6mm/s、送粉速率5g/min。
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.
