Abstract :
The influence of irradiation regimes by low energy intensive current electron beams of microsecond duration on chemical composition and phase-structural state of titanium alloy parts surface layers. It is shown that this treatment enables: to purify surface of details from the oxygen and carbon impurities; to improve the element distributions homogeneity in a depth; to decrease roughness of surface up to 0.05–0.07 µm; to modify the phase composition and structure of material in surface layer up to 10 µm thickness. In addition, the fatigue life can be increased in 80 times.
