The increased microhardness of a composite based on mechanically activated carbon and quasicrystals is one of the important aspects of modern materials science research. This composite combines the unique properties of both carbon and quasicrystals to provide improved mechanical properties.

Mechanical activation of coal promotes the formation of new surface defects and microstructural changes, which in turn increases its interaction with the quasicrystalline phase. When these two components are combined, a composite material is formed that has high hardness and wear resistance. Quasicrystals, known for their unusual symmetry and high strength, make a significant contribution to the mechanical properties of the composite.                                                        

Experimental studies show that such composites can achieve a significant increase in microhardness compared to the original components. This opens up new prospects for the use of such materials in areas requiring high strength and resistance to deformation, including mechanical engineering, aerospace and tool manufacturing.
