Investigation of the kinetics of the formation, structure, composition, and properties of electrospark coatings fabricated from modified TiC-KhN70Yu-BASED electrode materials applied on titanium alloy OT4-1

摘要

The influence of nanodispersed addition agents (ZrO_2, Al_2O_, W, WC, WC--, NbC, and Si_3N_4) on mass transfer of SHS-electrode materials based on TiC--KhNVOYu under differenttreatment energies is studied. A complex of studies of the properties of the electrospark coatings obtained (structure, phase composition, thickness, uniformity, microhardness, and high-temperature corrosion resistance) when applied to the titanium alloy OT4-1 is conducted. An optimal regime for the application of eleetrospark-alloying coatings by means of new modified electrode materials, performed on the Alier-Metal high-frequency plant (E = 0.13 J, f = 3000 Hz) is found. It is established that addition of a nanodispersed component to the electrode material helps to increase transfer, increases the thickness, uniformity, microhardness, and high-temperature corrosion resistance of electrospark coatings.
