Description
Summary:The effect of nanodispersed additives of ZrO^sub 2^, Al^sub 2^O^sub 3^, NbC, W, WC, and WC-Co into the composition of the TiC-Ti^sub 3^AlC^sub 2^ electrode on the kinetics of formation of coatings by electrospark doping (ESD) on the titanium alloy of the OT4-1 grade on varying the duration of pulsed discharges in a wide range is investigated. The structure, phase composition, properties (continuity, thickness, microhardness, friction coefficient, wear resistance, and heat resistance) are investigated. The optimum energy mode of the ESD treatment of the OT4-1 titanium alloys by new electrode materials is determined. It is found that the introduction of a nanodispersed component is favorable to an increase in continuity and the microhardness of electrospark coatings and a substantial increase in wear resistance and heat resistance of titanium alloys.[PUBLICATION ABSTRACT]
