Abstract This paper presents the test results of the swift krypton (240 MeV) and xenon ion (130 MeV) irradiation influence on the titanium surface layer properties. These ions change the titanium surface topography in different ways. The irradiation contributes to the creation of a new phase in the surface layer. Radiation damage effects on the friction coefficient, wear, and microhardness of titanium after krypton and xenon ion irradiation were studied. Krypton irradiation does not influence the microhardness of the titanium. After xenon irradiation with a fluence of 1 × 10 18 ion/m 2 the microhardness increases by 13%; further increases of the fluence gradually reduce the microhardness of the surface layer. Swift Kr and Xe ion irradiation does not influence the friction coefficient of the titanium surface.
