| Summary: | This work presents results in the field of synthesis of new metal matrix composites with matrix NiTi and particles TiB<sub>2</sub>, and their use as additives to fabricate metal matrix composites based on the Inconel 625 alloy. NiTi-TB<sub>2</sub> powders were obtained using self-propagating high-temperature synthesis. Composite NiTi-TiB<sub>2</sub> particles were spheroidized on a high-frequency induction plasmatron. Composite NiTi-TB<sub>2</sub> particles were mixed with metallic Inconel 625 powder with particle sizes of 50⁻150 µm. We used direct laser deposition by means of mixture of powders to grow samples with different contents of ceramics in the metal matrix. The process of direct laser deposition during the experiment was investigated. We have determined the peculiarities of the formation of the structure in metal matrix composites with different contents of titanium diboride. We have demonstrated the possibility of using Direct Laser Deposition (DLD) for fabricating items from ceramic metal materials. We have determined promising fields of further research for the purpose of obtaining efficient metal matrix composites using additive manufacturing technologies. |
