摘要/Abstract

摘要： 采用激光熔覆技术在50CrMnMo钢表面制备铁基涂层,结合仿真与试验研究扫描速度对熔覆涂层宏观形貌、微观组织与耐磨性能的影响,建立扫描速度与涂层宏观尺寸、温度场分布、微观组织(晶粒尺寸和形态)、硬度及耐磨性能之间的关系。结果表明,随着扫描速度的增加,涂层的熔高、熔深和熔宽均不断减小,温度场中最高温度逐渐降低,顶部等轴晶、中部柱状晶及底部胞状晶晶粒尺寸逐渐减小。仿真预测的冷却速度(G×R)、过冷参数(G/R)与试验对应的微观组织形态、尺寸吻合较好。扫描速度由8 mm/s增加至12 mm/s时,硬度逐渐增加,磨痕深度和磨损质量损失逐渐减少,耐磨性逐渐增强。以涂层宏观形貌、微观组织、硬度及耐磨性综合评价,最优扫描速度为12 mm/s。

Abstract: Iron-based coatings were prepared on 50CrMnMo steel surface by using laser cladding technology. The effects of scanning speed on the macro morphology, microstructure, hardness and wear resistance of the coatings were systematically investigated through combined simulation and experimental approaches. Relationships between scanning speed and coating macro dimension, temperature field distribution, microstructure characteristics (grain size and morphology), hardness and wear resistance were established. The results indicate that with the increase of scanning speed, the cladding height, penetration depth and coating width decrease continuously, the peak temperature of the temperature field decreases gradually, accompanied by grain size reduction in top equiaxed grains, middle columnar grains, and bottom cellular grains. The cooling rate (G×R) and undercooling parameter (G/R) predicted by simulation are in good agreement with the microstructure morphology and size corresponding to the experiment results. When the scanning speed increases from 8 mm/s to 12 mm/s, the hardness of the coating improves, while both the wear scar depth and mass loss decrease correspondingly, and the wear resistance is enhanced. Based on the comprehensive evaluation of macro morphology, microstructure, hardness and wear resistance of the coating, the optimal scanning speed is 12 mm/s.
