FIELD: carbon materials.
SUBSTANCE: carbon polymer contains homeotropically oriented carbon atoms and is made in the form of monocrystalline structure with tightly packed carbon atoms with sp-sp3 hybridization. Distance between adjacent carbon atoms in the same chain varies from 1.21 to 1.37 Å and chains are spaced from each other by 3.97 to 5.11 Å. Carbon polymer is prepared through vaporization of graphite by impulse arc discharge in vacuum chamber provided with one principal and two auxiliary plasma sources. Plasma beam is oriented onto substrate. Angle of plasma beam relative to substrate is varied depending on impulse parity. Atomically smooth film is thus prepared having coefficient of friction 0.05-.0.6 and showing wear and score resistance. polymer is further thrombus resistant and biologically compatible.
EFFECT: achieved high performance characteristics.
