Description

Increases in performance of power generating combustion turbine engines have driven up operating temperatures and placed greater demands on turbine components. To meet these increased demands, some components such as fan blades, are fabricated from Inconel and Udimet superalloys and are coated with 0.10 to 0.15 mm of NiCoCrAlY. This coating affords the blades protection against oxidation and particle erosion, and provides a degree of thermal insulation to lower blade operating temperatures.
