METHOD OF FORMING TITANIUM-BOR-copper coating on a copper contact surface

摘要

FIELD: metallurgy.;SUBSTANCE: weighed portion of amorphous boron powder is placed on titanium foil which is then exploded electrically with formation of a pulsed multiphase plasma jet. After that, this jet fuses the copper surface with a value of the absorbed density power of 6.5…7.6 GW/m² and saturation of the fused layer with the plasma jet components, followed by self-hardening and formation of a composite coating containing titanium diboride and copper.;EFFECT: improved electroerosion resistance of coating and its adhesion to base.;4 dwg, 2 ex
