摘要: 在数控机床刀具用W18Cr4V钢中添加不同含量的碳化钒和石墨烯,并进行耐磨损性能和热疲劳性能的测试与分析。结果表明,与单一添加相比,复合添加碳化钒和石墨烯对W18Cr4V钢耐磨损性能和热疲劳性能的改善效果更加显著。复合添加1.5%碳化钒和1.5%石墨烯使W18Cr4V钢的磨损体积减小81%,热疲劳裂纹级别从9级变为2级。Abstract: The wear resistance and thermal fatigue properties of CNC machine tool steel W18Cr4V with various content of vanadium carbide and graphene were tested and analyzed.The results show that complex adding vanadium carbide and graphene was better for improving the wear resistance and thermal fatigue property of W18Cr4V steel than single addition.Complex adding vanadium carbide of 1.5% and graphene of 1.5% could decrease the wear loss volume of W18Cr4V steel by 81%,and improve the thermal fatigue grade from grade 9 to 2 grade.
