The process of producing by mechanical alloying method the composite powders, based on FeMoNiCrB amorphizing alloy with additives of refractory compounds (ZrB2, (Ti,Cr)C і FeTiO3) by processing a mixture of component powders in planetary mill «Activator 2SL» was studied. It was found that after 1.5 h of processing its products are homogeneous conglomerates with average particle size, depending on the composition of composite powders, which was 23 ~m in the case of FeMoNiCrB+ZrB2, 15 ~m in the case of FeMoNiCrB+(Ti,Cr)C, and 25 ~m in the case of FeMoNiCrB+FeTiO3. XRFA results reveal formation of an amorphous-nanocrystalline structure in the produced powders, which consists of Fe(Ni,Cr), Mo2FeB2 solid solution and disperse phase of additives of refractory compounds (ZrB2, (Ti,Cr)C і FeTiO3) with indications of certain interphase interaction of FeMoNiCrB and (Ti,Cr)C. Here, the amorphous phase appears as a result of the process of mechanical alloying. The values of measured microhardness in composite powders were as follows: FeMoNiCrB+ZrB2 – 6.2±1.6 MPa, FeMoNiCrB+(Ti,Cr)C – 5.5±1.1 MPa, FeMoNiCrB-FeTiO3 – 5.1±0.7 MPa. For application in thermal spraying of coatings with an amorphous structure, the composite powders produced from mechanical alloying products are used to form conglomerate powders with particle size and degree of flowability, meeting the requirements of thermally-sprayed coating technology (plasma, detonation, high-speed gas-flame). 14 Ref., 3 Tabl., 12 Fig.
