Phase composition, structural state and mechanical properties of the ion-alloyed surface layer of titanium target implanted with Al ions have been investigated. Ion implantation of the Al ions into titanium was carried out using the vacuum-arc, ion-beam and plasma-flow source "Raduga-5". The implantation at the high intensity mode allowed to obtain the ion-alloyed layer with thickness equal to 2600 nm. By the transmission electron microscopy it was established that the fine dispersed equilibrium intermetallic phases Ti3Al, TiAl and the solid solution of aluminium in titanium were formed in the surface alloyed titanium layer. Additionally, the formation of TiAl3 phase was monitored by means of X-ray diffraction. It was established that the average size of precipitates of the formed phases was equal to 70 nm. Moreover, the agglomeration of the intermetallic particles up to size of 584 nm took place. It was established that the ion-alloyed Ti layer consisting the intermetallic phases was thermostable. The base phase composition remained the same after annealing at 473 K for 1 h. It was found out, that the mechanical properties of the implanted titanium were higher than of the unimplanted material. The microhardness of the implanted titanium sample was in 1.5-3 times higher than the microhardness of the unimplanted Ti. The wear of the implanted Ti was not changed in the temperature range 300-700 K.
