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.
