    Abstract

    The intermetallic phases in the surface layers of nickel and titanium were formed by means of high-intensity mid-energy implantation by Al ions on the installation equipped with an accelerated ion source 'Raduga-5' based on the continuous vacuum-arc discharge for the irradiation doses has been reported. The surface layers of metals consisting of intermetallides with nanodimensional grain parameters can intensely protect a bulk material. The formation of intermetallic structures in surface layers of metals can be successfully realized by bombarding the surface with high-intensity beams. The formation of the surface ion-doped layers of micron thickness under conditions of high-intensity ion implantation is provided by high implanted-element concentration gradients in the surface layer and the high temperatures arising during ion implantation. The thickness of phase localization areas and formed multiphase layers increases with the implantation time and, correspondingly, the irradiation doses.
