PROCEDURE FOR APPLICATION OF COMPOSITE LAMINATE MOLYBDENUM-COPPER COATING ON COPPER CONTACT SURFACE Russian patent published in 2011 - IPC C23C14/32 C23C14/14 

Abstract RU 2436864 C1

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. Also, layers of molybdenum and copper are alternated at successive propagation of electric current through foils. Electric current causes electric explosion of first molybdenum, than of copper foil. Products of explosion on contact surface are condensed at value of absorbed density of power 4.1...4.5 and 3.7...3.9 GWt/m2 correspondingly, while thickness of layers is changed by changing weight of exploded foil.

EFFECT: raised erosion resistance of coating and adhesion of coating to base and between layers of copper and molybdenum.
