Abstract
Considered are the results of carried out tests on evaluation of wear resistance of rotor blades of compressor of helicopter engine TV3-117 with ion-plasma coating (TiZr)N, formerly used only in the tool manufacturing. The tests on compressor blades were carried out under the conditions close to the conditions of operation of helicopter engine during take-off conditions. The results of coating test on resistance to corrosion in air-sea atmosphere correspond in average to nine points according to the ten-point scale. The assumption was made that rate of erosion of coating depends on its microhardness and air temperature in compressor unit of the engine. To describe and analyze these dependencies the mathematic method of leveling (method of the least squares) was applied. Quadratic function describes most precisely the practical results. The calculation quadratic curve of the second order correlates well with the experimental curve reflecting the dependence of rate of erosion on microhardness. The obtained working model provides possibility of carrying out the further calculations of service life of blades in different temperature ranges, i.e. evaluation of reliability of aircraft industry objects. 14 Ref., 4 Tables, 3 Figures.
