Abstract

The possibility of using ion-plasma coatings deposited by high energy vacuum-plasma technology to reduce the free end oscillations amplitude of VT6 titanium alloy samples during testing on vibrodynamic bench at resonance conditions by the first bending mode is hereby shown. The coatings based on pure Ti, Zr, Cr, Ni, Al, Cu metals deposited on the MAP-3 unit under modes enabling the coating growth in the range of 19–73 g/m2 while the tempera-ture of ion and radiation heating does not exceed tempering temperature of the VT6 titanium alloy is investigated. The tests on the damping capacity of applied coatings were performed. It is established that aluminum coating has the best properties.
