摘要：

Zirconia coatings represent an advanced materials technology that offers significant durability and performance benefits for marine gas turbines. Thin zirconia coatings offer superior resistance to hot corrosion attack from fuel (sulfur, vanadium, and sodium) andair (seasalt) impurities present in marine engine environments. Thicker zirconia coatings reduce transient thermal stresses and heat transferred into aircooled components. This paper describes the development of zirconia coatings, applied by the electron beam evaporation-physical vapor deposition process, that are tailored to provide superior durability in a marine engine environment. © 1990 ASME.
