Definition of Pre-Destruction Diagnostic Signs on Condition of Surface Layers of Heat Resistant Nickel Alloys

A Study of Fatigue Processes in the Material of the Compressor Blades of a Gas Turbine Engine After Long-Term Operation

“…The main types of damage to compressor blades during long-term operation are erosion and corrosion wear of the working surface, as well as fatigue failure. The analysis of the blade material with different operating times is an urgent task for studying fatigue processes and predicting the residual life of the parts [1]. Previously, we studied the condition the material compressor blades, which had operated within the assigned lifetime (with a run time of 50 000 to 60 000 hours) [2].…”
