Özet
This paper delves into the significance of creep failure in turbine blades exposed to high temperatures. Creep, a time-dependent inelastic deformation phenomenon, involves various microstructural rearrangements such as dislocation motion, microstructure aging, and cavitation at grain boundaries. Past studies focused on enhancing gas turbine quality through methods like film cooling, coating, and blade curvature, which aimed to protect the turbine blades from extreme temperatures of up to 1400°C within the turbine and extend their lifespan. However, these studies often overlooked their impact on engine efficiency. This research aims to improve gas turbine efficiency by evaluating the efficacy of turbine blades after applying coatings. As the turbine blade connects the turbine and compressor and provides energy to the compressor, its performance is critical for overall efficiency improvement.
