Development of a chemical alloy of composite metal-ceramic materials and parameters of their manufacturing process using additive technology of selective laser melting for rapid prototyping of products operated in extreme conditions of friction, wear and high-temperature oxidation.
popup.description2
The objective is to develop chemical compositions and technological parameters for fabricating metal-ceramic composites using the method of selective laser melting, specifically – Laser Powder Bed Fusion (LPBF) – for rapid prototyping and production of parts operating under intensive wear and high temperatures. Research Methods: Thermodynamic modeling (ThermoCalc, JMatPro), microstructural analysis (Olympus GX71 optical microscope, JEOL JSM-7000F scanning electron microscope), energy-dispersive X-ray spectroscopy (Oxford Instruments INCA Penta FET), and microhardness measurements. Key Results: The formation of composite structures based on Ni (Inconel 718), Co (Stellite 32), and steels (316L, Х12Ф, Р6М5) with refractory additives (TiC, NbC, TaC, TiB2) was analyzed using ThermoCalc and JMatPro. Phase diagrams and crystallization patterns were investigated. Optimal composite compositions were determined for various conditions, including electrochemical corrosion, high-temperature oxidation, erosion, and wear. The technological parameters for selective laser melting were established. Using a developed hybrid technology (SPS sintering followed by laser remelting), prototypes were fabricated and their microstructure was analyzed, confirming the feasibility of achieving the target phase state. Experimental samples of the developed metal-ceramic composites were successfully produced using the LPBF method.
