Abstract The Co-Mn composite material with excellent microstructure was prepared by the method of spark plasma sintering (SPS) at 800 ℃/45 MPa for 32 min. Morphology and characteristics of the material were discussed. Furthermore, the fitting degree of the SPS theory and actual process combined with the problem of fuse zone and sintering hole defects were analyzed, which was related to theories of molecule kinetics. It aims at optimizing the SPS procedure for Co-Mn composite material preparation and promoting the application of SPS theory in practical production.
