Abstract
Differences in wear rate, morphology of the worn surface and debris, and the microstructure in subsurface of the Ti-6A1-4V alloy after wear in air and vacuum were compared. The wear rate of the alloy in air is higher than that in vacuum in all the ranges of sliding velocities and applied loads. The wear of the alloy in air is controlled by a combination of abrasion, oxidation and delamination with microcracks remaining in subsurface. Under the vacuum condition, the surface layer of the alloy experiences a severe plastic deformation on a great scale, which results in an ultrafine microstructure.
