摘要
利用等离子堆焊工艺制备了Fe-Cr-B-C合金涂层,并对其进行了不同温度(850、950和1050℃)的淬火处理。利用OM、SEM、XRD研究了合金涂层不同温度淬火后的显微组织,利用显微硬度计对合金涂层的硬度进行了测试。结果表明:堆焊态Fe-Cr-B-C合金涂层的显微组织由树枝晶基体和网状硼碳化物组成;经1050℃淬火处理的Fe-Cr-B-C合金涂层网状硼碳化物回溶、球化,硬度达64.3 HRC,综合性能最优。
Effect of quenching temperature(850, 950 and 1050 ℃) on microstructure of Fe-Cr-B-C alloy coating prepared by plasma overlaying was studied by means of OM, SEM and XRD, and the hardness was tested by using microhardness tester. The results indicate that the as-plasma overlaid Fe-Cr-B-C alloy coating comprises dendritic matrix and interdendritic boron carbide distributed in the form of continuous network. After quenching at 1050 ℃, the boron carbide in the Fe-Cr-B-C alloy coating dissolves and spheroidizes, the hardness is up to 64.3 HRC, and the comprehensive properties is the best.
