Abstract

Electrospark treatment of OT4-1 titanium alloy was performed sequentially with a hard-alloy electrode STIM-20H (TiC—20% Ni) and carbon-containing material (graphites and carbon-based composite materials). Phase composition and relief of the coatings formed were analyzed. It was established that with regard to the applied carbon-containing material, the electrospark treatment can decrease the friction coefficient of the coatings and increase wear- and heat resistance of the titanium alloy.
