等温淬火球墨铸铁的滚动接触磨损性能研究

Rolling Contact Wear Property of Austempered Ductile Iron

  • 摘要: 将2种等温淬火球墨铸铁(Austempered Ductile Iron, ADI)和合金钢车轮材料分别与合金钢钢轨材料匹配,研究各摩擦副的滚动接触磨损性能.结果表明:与合金钢车轮材料相比,2种ADI材料的磨损性能均有大幅度的改善.硬度低、石墨球直径小且密度大的ADI材料自润滑效果好,相对应的摩擦副抗磨损性能最好;硬度高、石墨球直径大且密度小的ADI材料自润滑效果较差,相对应的摩擦副抗磨损性能居中;合金钢车轮材料不具备自润滑能力,相对应的摩擦副抗磨损性能最差.

     

    Abstract: Two austempered ductile irons (ADIs) and alloy wheel steel are matched with alloy rail steel and the rolling contact wear properties of these frictional pairs are investigated. The results show that the wear properties of two ADIs are improved significantly compared with the alloy wheel steel. The self lubricating capability of the ADI with low hardness, small and large quantity distributed graphite nodule is excellent, and the wear resistance of the corresponding frictional pair is the highest. The wear resistance of the ADI with high hardness, large and small quantity distributed graphite nodule is weak, and the self lubricating capability of the corresponding frictional pair is moderate. The alloy wheel steel is not self-lubricating, and hence the wear resistance of the corresponding frictional pair is the lowest.
