| Περίληψη: | Title screen The development of hybrid aluminum matrix composites (HAMCs) reinforced with superhard carbides is a crucial scientific direction, which still faces challenges related to the inhomogeneous distribution of reinforcing component and the formation of undesirable interphase compounds. This study was aimed to develop a universal in-situ approach for plasma dynamic synthesis of HAMCs with enhanced structural, mechanical, and functional properties. Dispersed powders of HAMCs reinforced with WC, SiC, and B4C were produced by high-speed spraying of a multicomponent thermal plasma jet, followed by spark plasma sintering (SPS) to fabricate bulk materials. The developed plasma processing technology provides complete alignment of the HAMCs components and form a composite structure with a polymodal particle size distribution, where the aluminum matrix is primarily presented with porous microsized particles filled in by ceramic component. These features of composite powders affect high mechanical properties of bulk sintered samples with density values of up to 99 % and microhardness values of up to 134 HV, which exceed those of known analogs and pure aluminum. A combination of high mechanical, thermal and electrical properties confirms the functionality of synthesized materials and highlights the potential of applying in-situ approach based on plasma processes for producing advanced HAMCs with improved performance characteristics Текстовый файл AM_Agreement |
