The challenge of preventing corrosion of gas turbine engines, with emphasis on military aircraft engines in marine atmospheres, is discussed. Differences between lower temperature corrosion and accelerated oxidation at high temperatures are described. Means of corrosion control include use of corrosion and oxidation resistant alloys and protective coatings such as silicone paints, ceramics, platings, and high-temperature coatings; criteria for their use on engine parts are reviewed.
