钇基重稀土对Cr12MoV钢耐磨性和热处理变形的影响

Effects of Y Based Heavy Rare-Earth on Resistance to Wear and Heat Treatment Deformation of Cr12MoV

探讨了钇基重稀土对 Cr12 Mo V钢耐磨性和热处理变形的影响。实验结果表明 ,微量重稀土显著地提高Cr12 Mo V钢的抗滑动磨损性能 ,对抗磨料磨损性能也有所改善 ,并减小 Cr12 Mo V钢的热处理变形。

This paper has investigated the effects of Y based heavy rare earth on resistance to wear and heat treatment deformation of Cr12MoV.The experimental results show that Cr12MoV's resistance to sliding wear is obviously raised,resistance to abrasive wear is also improved and dimensional deformation after heat treatment is reduced by trace heavy rare earth.
