In the present work, the characterization and production of CoTi intermetallic materials produced by electric current activated sintering under 300 MPa uniaxial pressure in open air at 2000 A for 6 min was investigated. Cobalt powder with 10 μm size and titanium powder < 40 μm size having 99.9% and 99.5% purity, respectively, were used. The elemental powders were mixed in the stoichiometric ratio corresponding to the CoTi intermetallic, in a molar proportion of 1:1. Scanning electron microscopy and X-ray diffraction analysis were used to characterize produced samples. In microstructural examinations it was found that the sample has multi-phase microstructure. X-ray diffraction studies revealed that the phases are CoTi, CoTi_2, TiCo_2, and CoTiO_3. The relative density of test materials measured according to Archimedes' principle was 87.6%, and the microhardness of materials was about 646.74 HV_{0.1}.
