Ti-Y Surface Alloy Formed by High-Energy Methods

Abstract:

The alloying of the titanium layer by yttrium is carried out with the combined method of electroexplosive alloying and the subsequent radiation by a high-intensity electron beam. The research of structure, element and phase composition, mechanical and tribological properties of the alloyed layer is executed. The saturation of the titanium layer by atoms of yttrium, oxygen and carbon that leads to formation of oxides and carbides of the titanium and yttrium is revealed. The formation of two types of an eutectic is established. It is shown that the eutectic enriched with the titanium has a globular form when the eutectic enriched with yttrium has a plated one. The multiple increasing of microhardness, decreasing of friction coefficient and the wear rate of the alloyed layer is revealed.
