Abstract: PROBLEM TO BE SOLVED: To prevent heat deterioration by using a coating material on a compressor part of a turbine part. SOLUTION: Seawater is made to remain as hemispherical droplets rather than forming a water film as it spreads on a blade in the case when seawater remains by restraining wetting by sea water on the blade by increasing a contact angle at more than about 50 deg. by covering a thin coating material capable of extremely preventing wetting by seawater and having an adhesive property on a metal member of a compressor part including the blade and a vane. Consequently, it is possible to reduce seawater remaining on a blade surface and to reduce formation and accumulation of salt on a constitutional member of the compressor part. Accordingly, crystal salt never concentrates on the blade of the turbine part and the droplets pass through the inside of a gas turbine engine as they are droplets.

Abstract: A compressor coating is described which can reduce corrosion in the turbine system of a gas turbine engine. The coating is essentially not wet by droplets or aerosols of sea water or other corrodants. The coating reduces the build up of salt deposits on compressor components and their subsequent passage into the turbine section, thereby preventing severe localized corrosion which would otherwise occur.
