摘　　要：以Mo、N i、Cr、Fe与FeB为原料,制备出适合于反应火焰喷涂的复合粉末,并采用亚音速反应火焰喷涂技术制备出三元硼化物金属陶瓷涂层,用扫描电镜(SEM)和X射线衍射(XRD)对其形貌及相成分进行分析,并用显微硬度计对涂层的显微硬度进行测定。结果表明:经过反应火焰喷涂后,粉末发生反应生成了Mo2FeB2,并以颗粒状弥散分布,其涂层的显微硬度达到1 400 HV。The paper particles for reactive flame spraying and the fabricating of the ternary boride cermet use Mo,Ni ,Cr,Fe and FeB as raw material. The microstrueture morphology and the phase of the coating are analyzed by SEM and XRD. The micro - hardness is tested by the micro - hardness tester. The results show that the particles turn into the Mo2FeB2 and distribute in the coating. The micro - hardness of the coating reaches 1 400 HV.
