摘要

FIELD: electricity.;SUBSTANCE: method includes electrical explosion of composite conductor exploded electrically that consists of a double-layer flat copper shell with the mass 60-360 mg and core in the form of wolfram and graphite or technical carbon powders taken in stoichiometric ratio for synthesis of carbonaceous wolfram with total weight equal to 0.5-2.0 of the shell weight, formation of a multiphase pulsed plasma jet out of explosion products, melting of the surface of a copper electric contact by the jet at absorbed power density 4.5-6.5 GW/m², deposition of the explosion products to the surface and formation of the composite coating of W-C-Cu system at it and subsequent repetitively-pulsed electron-beam treatment of the coating surface at absorbed power density 40-60 J/cm², pulse duration 150-200 mcs and the number of pulses 10-30.;EFFECT: invention allows to fabricate contacts with high electroerosion resistivity.;2 ex, 2 dwg
