| 中文摘要: |
| 目的 探讨FeAlNbB涂层的制备方法，研究FeAlNbB涂层的组织结构及摩擦磨损行为。方法 通过超音速电弧喷涂技术制备FeAlNbB涂层，采用扫描电镜（SEM）、X射线衍射仪（XRD）分析FeAlNbB涂层的组织结构及相组成，并利用显微硬度计和摩擦磨损试验机对FeAlNbB涂层的硬度及摩擦学行为进行研究。结果 FeAlNbB涂层主要由α-Fe、Fe3Al、FeAl相组成，涂层的平均硬度为700HV。在试验参数下，涂层的摩擦系数在0.2~0.4之间，涂层的耐磨性为20#钢的12~33倍，涂层的磨损机理主要以犁沟效应和磨粒磨损为主。结论 超音速电弧喷涂制备的FeAlNbB涂层与基体结合良好，组织致密。涂层中无非晶组织，但涂层的硬度、耐磨性能与FeAlNbB非晶态涂层相当。 |

| The work aims to study structure as well as friction and wear behavior of FeAlNbB coating by discussing preparation method of the coating. FeAlNbB coating was prepared by adopting supersonic electric arc spraying technology. Structure and phase composition of FeAlNbB coating were analyzed by using SEM and X-ray diffractometer. Hardness and tribological behavior of the FeAlNbB coating were studied by using microhardness tester and friction-wear tester. The FeAlNbB coating was mainly composed of α-Fe, Fe3Al and FeAl phases. Average hardness of the coating was 700HV. Provided with test parameters, friction coefficient of the coating ranged between 0.2~0.4, wear resistance of the coating was 12~33 times as high as that of 20# steel, and wear mechanism of the coating was mainly plowing effect and abrasive wear. The FeAlNbB coating prepared by supersonic electric arc spraying is compact and well bonded to the substrate. There is no crystalline structure in the coating, but hardness and wear resistance of the coating are equivalent to that of FeAlNbB amorphous coating. |
