First stage blades in an Industrial Gas Turbine (IGT) face an extreme combination of mechanical stress, creep, hot corrosion and high temperatures. For example, gas temperatures can reach up to 1600 to 1700 °C (2912 to 3092°F). Besides these high temperatures, IGT coatings need to have excellent thermal cyclic life to withstand many hours of operation. Their surface coating design therefore is critical for the energy efficiency of the whole system.
Longer Component Life for Hot Section Blades
Turbine blades are the most demanding applications in IGTs. As temperatures increase in IGT engines, new coating challenges occur: phase stability, sintering resistance, oxidation of the bond coat and CMAS (calcium-magnesium-alumina-silicate) resistance.
