The properties of compressor blades of a helicopter gas-turbine engine with an experimental ionplasma coating Zr−Cr−N, are compared to those with Ti−Zr−N basic composition. It is shown that, due to the structural properties, the experimental coatings make the blades more corrosion-resistant, and mitigate the dependence of their residual properties on the amplitude and the temperature of the preliminary vibrotempering.
