Severe hot corrosion of gas turbine blades and vanes can result from the use of fuels contaminated with sodium and sulfur. A program has been initiated to survey currently available commercial as well as advanced developmental hot corrosion resistant coatings and select a list of coatings for application to Solar Centaur first-stage blades and vanes. A subsequent engine test program will be run on high-sulfur marine diesel fuel doped with sodium to produce severe hot corrosion conditions. The coatings will be tested in a rainbow fashion for a period up to 15,000 hours.
