The metal-matrix composites reinforced by the fullerenes

Abstract

The method of the high voltage electric discharge (HVED) treatment in the kerosene (the dispersion, the activation and the synthesis) is proposed to obtain the new anti-friction alloys based on TiC – AlC – and FeC with inclusions of the Cn0 (n=6 or 7) phases which are characterized by the high heat resistance, the strength and the durability to be used in the aircraft and in the rocket technology. The method is distinguished by the hardening particles, which are not mechanically added to the powder mixture, but instead they are synthesized during the HVED treatment of the “kerosene – Fe (Al) – Ti powder mixture” the disperse system with its simultaneous grinding what enable us to create the composite material with the increased mechanical and performance characteristics. The obtained alloys contain the refractory components (the fullerenes, the carbides), the MAX-phases of the Ti-Al-C system as shown by the micro-Raman data.
