Abstract

The surface layer of titanium is modified via a combined method involving electroexplosive alloying by yttrium and subsequent high-intensity electron-beam irradiation. The elemental and phase composition, defect substructure, and mechanical and tribological characteristics of the alloyed layers are investigated. The titanium-surface layer is revealed to be saturated with yttrium, oxygen, and hydrogen atoms, which give rise to the formation of a metal-ceramic layer hardened with titanium and yttrium oxides and carbides and stimulate a manifold increase in the microhardness and a decrease in the friction coefficient and wear rate of the modified layer.
