The effect of ultrasonic treatment before ion implantation of the VT6 titanium alloy with silver on the thickness of the ion-doped layer, the distribution of silver over the thickness of this layer, and the scalar density of dislocations in the subsurface layer are considered. It is established that for the VT6 alloy, with the same parameters of the implantation mode, the implementation of preliminary ultrasonic treatment leads to a decrease in the thickness of the ion-doped layer, an increase in the concentration of embedded silver and the scalar dislocation density in the sublayer with the induced dislocation structure. Complex treatment including ultrasonic treatment and ion implantation reduces the wear of irradiated VT6 alloy samples.
