Description
Summary:The phase composition, structural state and mechanical properties of the ion-alloyed surface layers of titanium implanted by the Al ions have been investigated. Ion implantation of the Al ions into titanium was carried out using the plasma-flow, vacuum-arc ion source "Raduga-5". It was found out that increase of the dose of Al ions from 2.2/spl middot/10/sup 17/ ion/cm/sup 2/ to 2.2/spl middot/10/sup 18/ ion/cm/sup 2/ led to the increase of the ion-alloyed layers thickness from 400 nm to 2600 nm. It was established that the fine dispersed equilibrium intermetallic phases Ti/sub 3/Al, TiAl and the solid solution of aluminium in titanium were formed in the ion-modified layers. The increased average size of the intermetallic particles took place with the irradiation dose increasing. The agglomeration of the nanoscale particles occurred above the dose 6.2/spl middot/10/sup 17/ ion/cm/sup 2/. It was found out, that the mechanical properties of the implanted Ti were higher than of the unimplanted material.
