Electrospark treatment of ОТ4-1 titanium alloy was performed sequentially with a hard-alloy electrode СТИМ-20Н (TiC-20%Ni) and carbon-containing material (graphite, composite materials based on carbon). A complex of investigations of the structure, composition and properties of the formed coatings has been carried out. It has been established that depending on the applied carbon-containing material, the electrospark treatment can favor decreasing the friction coefficient as well as enhancing the wear-resistance and scale resistance of the titanium alloy.
Keywords: electrospark deposition, self-propagating high-temperature synthesis, electrode material, coating, pulse discharge, carbon-containing materials, wear resistance, heat resistance, coefficient of friction.
