研究了含钒蠕墨铸铁与钢盘对磨时的干摩擦学性能。结果表明，钒的加入降低了蠕墨铸铁的磨损量，提高了接触压力和摩擦速度变化时磨损量的稳定性。含钒０．１％和０．３％（质量分数）时，提高了摩擦系数和高接触压力、高摩擦速度下摩擦系数的稳定性。含钒０．３％（质量分数）的蠕墨铸铁具有最小的磨损量和最大的摩擦系数。 The dry tribological properties of vanadium-bearing vermicular graphite cast iron and steel were studied. The results show that the addition of vanadium reduces the wear of compacted graphite cast iron and increases the stability of the wear amount when the contact pressure and the friction speed change. Containing vanadium 0.1% and 0.3% (mass fraction), improve the friction coefficient and high contact pressure, friction coefficient at high friction speed stability. The vermicular graphite cast iron with 0.3% (mass fraction) vanadium has the smallest amount of wear and the largest coefficient of friction.
