The effect of powerful pulsed ion beam treatment on physical and chemical state of surface layers and fatigue strength of EP 718 ID alloy

Abstract

With the purpose to increase exploitation characteristics an effect of nanosecond powerful ion beam treatment regimes on physical and chemical state of surface layers and fatigue strength of samples and articles (compressor blades of gas-turbine engine) made of EP718ID nickel alloy has been investigated. Fatigue life of the alloy is shown to be able to be increased by 20% using irradiation (under not very high current densities about 60 A/cm²) and finishing heat treatment. Suppression of cavitation mechanisms under high current densities will make it possible to achieve even higher hardening of articles surface layers by means of the treatment under current densities of 100-200 A/cm².
