Abstract
The influence of uninterrupted and arc-pulsed ion implantation, high-power ion beam treatment and final annealing regimes on the chemical composition and phase-structural state of surface layers and on the surface properties of gas turbine engine compressor blades manufactured from refractory alloys was investigated. Long-term full-scale tests of the production and irradiated compressor blades were carried out under gas turbine engine operating conditions. After completion of the tests the physical-chemical state of the blades was studied.
