A surface alloy of the yttrium/titanium system, enriched with oxygen atoms, has been developed using high-energy methods. Formation of a multilayer multiphase submicron-and nanoscale structure has been revealed. A substantial increase in the microhardness (by ≈3 times), a decrease in the friction coefficient (more than by 2 times) and the wear rate (by ≈3 times) of the doped layer have been revealed.
