Conclusions

  1. 1.

    The VT3-1 and VT8 alloys have exceptionally low damping properties (the oscillation decrement varies in the range 0.02–0.09%) which may result in a severe vibrational stress state of members of the structures made of these materials.

     
  2. 2.

    The deposition of coatings containing electrolytically precipitated copper, nickel, chromium and also enamel with a total thickness of 90–130μm, on the specimens of the VT3-1 and VT8 alloys increased the damping characteristic (the decrement of bending oscillations) by 16–60 times at room temperature and by 22–83 times at a temperature of ≈250°C.

     
  3. 3.

    Of the coatings tested, preference should be given (with other condition being equal) to the four-layer coatings whose total thickness is smaller than that of the three-layer coatings.
