Heavy-duty gas turbines are essential for power generation and various industrial processes, requiring materials that can endure a wide range of degradation mechanisms, including oxidation, high-temperature corrosion, thermal stress, vibration, erosion, and wear. State-of-the-art turbines, which run intensive work cycles, are treated with numerous coatings that make their operation possible and cut down costly maintenance.
This paper provides a comprehensive review of thermal spraying techniques such as air plasma spraying and high-velocity oxygen fuel spraying, emphasizing their specific applications in components of heavy-duty gas turbine.
Кey issues of applying thermal spray coatings on gas turbine parts include: long-term performance prediction and inspection techniques.
Forecasting the long-term performance of thermal spray coatings under actual operating conditions is difficult due to the intricate interactions among the coating, substrate, and environment. This often necessitates extensive accelerated life testing and computational modeling.
Conventional inspection methods may fall short in adequately evaluating the integrity of thermal spray coatings.
