The paper has been intended to present non-destructive methods for the assessment of health of gas turbine blades in turbine and turbojet engines. Results of the assessment of changes in health/maintenance status of blades exposed to high temperatures have been discussed. All the findings gained with such methods have been successfully verified in the course of testing work carried out with some metallographic...
The processes associated with operation of traction, marine and avionic turbine engines entail occurrence of various defects affecting turbine components, in particular turbine vanes. The main reasons for defects and deterioration of gas turbine vanes include thermal fatigue and overheating of the vane material. This is why continuous monitoring of technical condition demonstrated by crucial engine...
