Abstract
A TURBINE BLADE HAS AN AIR FOIL (12), A ROOT (14) AND A PLATFORM (16) LOCATED BETWEE THE AIRFOIL (12) AND ROOT (14). THE PLATFORM (16) HAS AN UNDERSIDE ADJACENT THE ROOT, AND A CORROSION RESISTANT OVERLAY COATING (21;24) SUCH AS AN MCRAI 1Y OR A NOBLE METAL CONTAINING ALUMINADE OR CORROSION INHIBITING CERAMIC IS LOCATED ON PORTIONS OR THE BLADE NOT PREVIOUSLY COVERED WITH SUCH COATINGS, E.G., THE UNDERSIDE OF THE PLATFORM AND THE NECK (19). THE APPLIED COATING PREVENTS CORROSION AND STRESS CORROSION CRACKING OF BLADE IN THESE REGIONS. WHERE THE AIRFOIL IS ALSO COATED, THE AIRFOIL COATING MAY HAVE A COMPOSITION DIFFERENT FROM THAT OF THE COATING ON THE UNDERPLATFORM SURFACES.[FIG. 1A].
