Structure and properties of the superelastic and hard carbon particles reinforcing wear-resistant composite materials obtained from mixtures of iron and fullerene powders under pressure

摘要: The structure and mechanical properties of hard superelastic carbon particles formed at a pressure 5 GPa 1200–1400°C upon the consolidation metal-fullerene powder mixture into composite material have been studied by optical microscopy, high-resolution electron nanoindentation, etc. reinforcing are characterized an elastic hardness up to 15 GPa, high recovery (80–90%), modulus 60–90 low density (about 2 g/cm3), cracking resistance. X-ray amorphous, but they inherit pattern initial fullerite crystals. metallic materials reinforced in abrasive resistance surpass well-known wear-resistant steels order magnitude approach diamond-like coatings their friction coefficients 0.12).
