Abstract

The dependence of the damping ability of the thickness of new developed coatings system Al–Ni–Y during the vibration in the first bending form the resonance with the same amplitude of the exciting force corresponding to a stress of 70 MPa in the threat section. We investigated the surface roughness of titanium alloy VT6 after application of the damping coating. Investigated the erosion resistance of the new developed coatings system Al–Ni–Y, and the damping ability after exposure to the abrasive stream. Work was performed within the framework of strategic directions 17. «Comprehensive anticorrosion protection, hardening, wear-resistant protective and heat-resistant coating», сomplex problem 17.3. «Multilayer heat-resistant and heat-resistant coating, nanostructural hardening of erosion and corrosion-resistant, wear-resistant, antifatigue coating to protect parts hot gas path and compressor of GTE and GTU» («The strategic directions of development of materials and technologies of th
