Description

By means of AES, SEM, TEM, X-ray diffraction, exoelectron emission as well as by optical metallography in polarized light physical and chemical properties of the surface layers of heat-resistant Ti-based alloys (VT6, VT8, VT9) for application in aviation gas turbine engines exposed to power pulsed ion and electron beams have been investigated. A comparative fatigue tests as well as corrosion and erosion ones of initial serial and irradiated turbine blades were carried out. Perspective fields for the pulsed ion and electron beams application are chosen

Abstract (Russian)

Методами оже-спектроскопии, сканирующей электронной микроскопии, рентеноструктурного анализа, просвечивающее электронной микроскопии, экзоэлектронной эмиссии и оптической металлографии в поляризованном свете исследовано физико-химическое состояние поверхностных слоев лопаток компрессора и вентилятора из титановых сплавов ВТ6, ВТ8 и ВТ9, облученных мощными ионными и электронными пучками. Проведены сравнительные усталостные, коррозионные и эрозионные испытания, в том числе натурные, серийных и облученных лопаток. Выделены перспективные области применения импульсных ионных и электронных пучков
