Abstract:Fe-Cu-Mo-C alloys were prepared by mechanical milling and vacuum sintering. The effect of sintering temperature on the microstructure, density, tensile strength, friction and wear properties of the Fe-based powder metallurgy Fe-Cu-Mo-C was studied. Results show that the pores reduce and its size decreases when sintering temperature increases from 1 000 ℃ to 1 100 ℃; while the pore size increases when sintering temperature increases to 1 150 ℃. The relative density, hardness, tensile strength and elongation of the sintered body increase firstly and then decrease with the increase of sintering temperature. The mass wear of as-sintered sample decreases firstly and then increases with the increase of sintering temperature. The optimum performance is obtained for samples sintered at 1 100 ℃, with sintered density of 6.90 g/cm3, tensile strength of 319 MPa, hardness of 34.7 HRC and mass loss of 0.087 g.
