MODIFICATION OF THE SURFACE OF THE VT6 ALLOY BY ELECTROEXPLOSIVE TWO-COMPONENT ALLEGATION AND ELECTRON BEAM IRRADIATION

Abstract

Titanium-based alloys are widely used as structural materials in the aviation industry for the manufacture of components and parts belonging to the α+β alloy class. Electroexplosive alloying (EEA) is a promising method for protecting the surface of parts made from these alloys. This treatment simultaneously improves the physical, mechanical, and operational properties, including microhardness, heat and wear resistance under abrasive wear and dry sliding friction, and resistance to fretting corrosion. Further improvements in the properties of the material's surface layer and the product as a whole are achieved through combined treatment, combining EEA with subsequent electron beam treatment (EBT) of the modified surface. Compared to the widely used laser technology, electron beam technology offers greater control and regulation of the amount of energy supplied, is characterized by localized energy distribution in the near-surface layer of the material being processed, and exhibits a high efficiency.
