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。
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.
