| 摘 要： | 采用激光辐照对FeCrAlW电弧喷涂层的组织进行致密化处理,借助扫描电镜和X衍射对涂层的组织进行了分析.测试了涂层的显微硬度.结果表明:涂层组织致密度提高,孔隙率明显降低.随着激光扫描速度的增加,涂层的显微硬度降低.在较低的扫描速度下,涂层与基体之间形成互熔区,涂层与基体之间产生良好的冶金结合.

| Abstract: | Laser heating compact process of FeCrAlW was carried out, and the microstructure was analyzed and micro-hardness profile in the coating was examined by XRD and SEM. The results show that compact microstructure of the coating is obtained, pore and inclusion decrease. With increasing specific scanning speed, the micro-hardness of compact layers descends. When the scanning speed is lower, metallurgy combine between compact layers and substrate is obtained. |
