PROCEDURE FOR APPLICATION OF PSEUDO-ALLOY MOLYBDENUM-COPPER COATING ON COPPER CONTACT SURFACE

摘要

FIELD: metallurgy. ^ SUBSTANCE: according to procedure concentrated flows of energy are used for evaporation of source materials of molybdenum and copper and their condensation on contact surface. As source materials there are used thin foils of molybdenum and copper. Evaporation is performed at successive transmission of electric current through them causing electric explosion of first molybdenum, than of copper foil. Also, products of explosion are condensed on contact surface at value of absorbed density of power 6.0Ç7.6 and 7.6Ç10 GW/m2 correspondingly. ^ EFFECT: increased erosion resistance of coating and its adhesion to base. ^ 3 dwg, 2 ex
