Abstract

Systematized investigations of formation laws of surface layer complex properties and of endurance of intergrooves bulges of compressor disks from nickel base superalloy were carried out. Linear regression equations of hardening coefficient have been received, which made it possible to select rational methods and conditions of surface finish, and to make prognoses about disks endurance, taking into account all influencing factors 1 Introduction Disks of rear stages of axial high pressure compressors of gas turbine engines ( GTE) operate at moderately elevated temperatures (500° to 600 °C), high peripheral velocitie
