摘 要: | 采用粉末冶金工艺制备基体致密、表层多孔含油的双层复合铁基粉末冶金材料,用HDM-20端面摩擦磨损试验机评价其摩擦磨损性能。结果表明,当复层材料表层的孔隙率约为23%时,试样稳定运行时间长,减摩耐磨性能好;与相近孔隙率的单层材料相比,复层材料的减摩耐磨性能与承载能力得到明显提高。

Preparation of iron-based powder metallurgy multi-layer material and its tribological performance analysis |

Abstract: | Double layer iron-based composite material with dense matrix and porous oil-bearing surface was pre-pared by powder metallurgy method. The friction and wear properties were investigated on an HDM-20 tribo-tes-ter. The results show that when the porosity of surface is about 23%,the sample has long stable operation time, good friction-reducing and wear-resistance performance. Compared with single layer sample with similar porosity, the multi-layer samples have obvious improvement on anti-friction and wear resistance performance,as well the bearing capacity. |
