摘要采用超声振动辅助激光熔覆对EA4T钢表面进行修复，利用光学显微镜（OM）、扫描电镜（SEM）和X射线衍射仪（XRD），对比分析超声振动对EA4T钢激光熔覆成形质量、微观组织和物相组成的影响，通过显微硬度仪对熔覆层和基体的显微硬度进行测试。结果表明：超声振动作用下，熔覆层成形质量得到提高，原来方向性较强的枝晶组织被打断、打碎，枝晶偏析程度显著减轻；与此同时，施加超声振动晶粒得到细化，促进Cr₂₃C₆碳化物在枝晶上析出，但并未改变熔覆层物相组成；相比较未施加超声振动，超声振动作用下的熔覆层显微硬度分布更加均匀，平均显微硬度提高126.2HV_0.2，热影响区平均显微硬度下降31.2HV_0.2。

Abstract：The surface of EA4T steel was repaired by ultrasonic vibration assisted laser cladding.The influence of ultrasonic vibration on the forming quality, microstructure and phase composition of laser cladding of EA4T steel were compared and analyzed by optical microscopy (OM),scanning electron microscopy(SEM),X ray diffraction(XRD),and the microhardness of the cladding layer and matrix was tested by microhardness tester.The results show that the cladding forming quality is improved, and the dendritic structure with strong original orientation is broken under the effect of ultrasonic vibration,which reduces the segregation of dendrites within the cladding layer.At the same time,ultrasonic vibration refined grain, promotes the precipitation of Cr₂₃C₆ carbide on the dendrites, but it does not change the phase composition of cladding layer.Compared with that without ultrasonic vibration applied,the microhardness distribution of cladding layer is more uniform under the ultrasonic vibration, the average microhardness of cladding layer is increased by 126.2HV_0.2,and the average microhardness of heat-affected zone is decreased by 31.2HV_0.2.

Key words： laser cladding ultrasonic vibration microstructure microhardness
