The results show that the NbC strengthened Fe-CrC hardfacing alloy has higher hardness and better abrasion wear-resisting property. The hardness of NbC strengthened Fe-Cr-C hardfacing alloy reach to 61.7 HRC,9.5% more than Fe-CrC hardfacing alloy.

• 结果表明；NbC增强Fe-Cr-C耐磨合金的宏观硬度和耐磨性都高于Fe-Cr-C合金；宏观硬度达到61.；6 HRC；比Fe-Cr-C耐磨合金提高9
