Abstract

In this research we investigated the possibility of reducing the vibration amplitude of the free end of a flat sample during vibration tests on the first bending form due to the application of different types of surfaces on the sample shank when it is fixed in the technological capture on the equipment for the vibrodynamic stand. The dependence of the q-factor of the oscillating system on different types of coatings, the thickness of which is ~30 microns, and the tribological characteristics of the coatings are

investigated. It is shown that the solid-lubricant coating VFP-5 increases damping, reducing the amplitude of the free end of the sample during vibration tests on the first bending form. The coating based on the aluminum alloy VSDP-28, does not significantly reduce the amplitude of the free end of the sample and the ion-plasma coatings of the TiN/CrN, Ti–TiN and SDP-2 systems reduce the damping properties of samples from the titanium alloy VT6.
