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。
The wear resistance and thermal fatigue properties of CNC machine tool steel W18Cr4Vwith various content of vanadium carbide and graphene were tested and analyzed. The results show that com- plex adding vanadium carbide and graphene was better for improving the wear resistance and thermal fa- tigue 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 ther- mal fatigue grade from grade 9 to 2 grade.
