Protection of Superalloys for Turbine Application

Superalloys are so named because they retain useful strength to temperatures approaching 2000°F (1093°C). Unfortunately, the alloying elements responsible for imparting high-temperature strength are often responsible for lowering the alloy’s resistance to aggressive environments. Since superalloys are used extensively in aircraft, marine, industrial, and vehicular gas turbines, where some of the most severe environments are encountered, this lack of environmental resistance proves to be a serious problem. Attention has therefore been focused in recent years on developing suitable coatings and claddings.
