Application of high-concentrated energy flows for producing nanostructured polyfunctional composite materials (NAPOCOM)


Project no.: S-LU-22-10

Project description:

Dispersible Ti-Al-C and TiC-Fe-C system composites are widely used in the aerospace industry due to their inherent properties in metals (sufficient toughness and impact strength) and ceramics (high strength and modulus of elasticity). These composite materials consist of a metal matrix and particles that harden it. Their strength is highly dependent on the size of the hardening particles. Dispersed hardening particles – carbides and MAX-phases, increase the abrasion resistance of composite materials several times. The project will develop a powder production method that allows to obtain the required powder mixture in a relatively short time and with lower energy consumption compared to the traditional mechanical powder milling method. This will be achieved by allowing a high voltage energy discharge (HVED) in the “powder mixture – hydrocarbon liquid” suspension.

Project funding:

Intergovernmental programme administrated by Research Council of Lithuania: Lithuania–Ukraine

Project results:

New nanostructured multifunctional composites based on Ti – TiC, Ti2AlC MAX phases and Ti3AlC carbides are expected to be developed. The implementation of the project includes the development of technology for the development of nanostructured multifunctional composite materials using highly concentrated energy streams. The synthesis of nanostructured composite powder mixtures will be performed using high voltage electrical discharge in a hydrocarbon liquid. The developed technological process is planned to be harmonized with the production requirements adopted by the European Union.
