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). Kinetics of the mass transfer of the hard-alloy electrode has been investigated. The cathode mass loss after the first minute of the treatment has been established. The kinetics results have been processed using methods of mathematical statistics. The erosion resistance of the applied carbon-containing materials has been determined. The phase composition and relief of the formed coatings have been studied It has been shown that application of the carbon-containing materials raises the content of refractory phases in the coatings. Increasing the time of the treatment with carbon-containing materials favors decreasing the roughness of the coatings.
