  • Structure and properties of superelastic hard carbon phase created in fullerene-metal composites by high temperature-high pressure treatment

    • Treatment of a fullerene soot extract and metal (Co) powder mixture under pressure of 5 and 8 GPa at 1000 °C leads to the transformation of fullerites into superelastic hard phase (SHP) and to simultaneous sintering of the powder mixture to nonporous composite material reinforced by the SHP particles. The structure of the SHP particles reveals a topological relation to the initial fullerite crystal morphology. Upon indentation, the SHP particles demonstrate an elastic recovery of up to 96. The universal microhardness of the SHP particles HU=26 GPa, and their microhardness HV = 35 GPa. A high ratio between the microhardness and elastic modulus (HV/E = 0.19-0.21) of the SHP particles makes them perspective candidates for design of materials with superior wear resistance and tribological properties.

  • Effect of high-pressure treatment temperature on the structure of carbon phases formed from C60 fullerites under pressure
  • 2019
  • Ingår i: Fourth interdisciplinary scientific forum with international participation "New materials and promising technologies" 27–30 November 2018, Moscow, Russian Federation. - : Institute of Physics (IOP).
  • Konferensbidrag (refereegranskat)abstract
    • The synthesis of metal-matrix composite materials reinforced with superelastic hard carbon particles formed from C60 fullerites includes heating of the metal-fullerite powder mixture to temperatures above 800C under pressure. The structure evolution of the carbon particles upon heating from 700 to 800 C at a pressure of 5 GPa has been studied in detail by Raman spectroscopy and indentation hardness measurements. It is shown that the structure of the carbon particle passes the stage of a nanoscale mixture of one- and two-dimensional polymers with the resulting atomic superelastic solid phase. The determining properties of the carbon particles such as superplasticity and high hardness are attained before the complete disappearance of polymerized fullerites, the remnants of which are responsible for the disintegration of the material upon scratching.
