Electrospark-Deposited Coatings from Titanium and Tungsten Carbide Alloys: Mass Transfer Kinetics, Structurization, and Properties

New WC, TiC, and TiB 2 electrode materials have been developed for hard wear-resistant electrospark-deposited coatings on a metal substrate. The phase formation and structurization during hot pressing of these materials are studied. The effect of electrode production process on the mass transfer and coating properties is analyzed. The alloys have fine structure with 1–2 μm grains of the major fraction and 26–30 GPa hardness. The structure and functional properties of the electrospark-deposited coatings are examined. Their hardness is 14–24 GPa and thickness 40–120 μm. The new electrode materials show significantly higher scale resistance than T15K6 alloy coatings, and their abrasion and wear resistance in dry friction conditions suggests that they may be efficiently used to strengthen rapidly wearing parts of machines and mechanisms.
