Abstract Using CuCl2·2H2O, FeCl2·4H2O, SnCl2·2H2O and NiCl2·6H2O as raw materials, H2C2O4·2H2O solution as precipitator, Cu-Fe-Sn-Ni quaternary Cu-based pre-alloyed powder was fabricated by co-precipitation method. The sintered Cu-Fe-Sn-Ni cupric carcass and the carcass/diamond caking were prepared through hot pressing processes. The effects of charging sequence, pH value, aging time, co-precipitation temperature and solution concentration on the particle size of precursor powders were investigated. The phase composition and morphology of the powder were characterized by X-ray diffraction (XRD) and scanning electronic microscope (SEM). Moreover, the flexural strength of Cu-Fe-Sn-Ni quaternary pre-alloyed powder was tested, which was compared with that of the samples that was prepared by mixing the four kinds of elemental powders. The results show the optimal process of Cu-Fe-Sn-Ni pre-alloyed powder is a parallel-flow charging sequence, co-precipitation temperature of 50 ℃, aging time of 40 min and solution concentration of 1 mol/L. The ultrafine Cu-Fe-Sn-Ni pre-alloyed powder with particle size of about 500 nm can be obtained by calcining and hydrogen reducing the precursor powder. The flexural strength of the matrix is 1 302 MPa and the carcass/diamond caking is 853 MPa after hot pressing.
