Abstract (en)
A turbine blade for a combustion turbine, in which the blade is provided with a hot-end coating, a cooler-end coating, and an intermediate transition zone with a mixture of the two end coatings. The blade has a hot end portion operable at a temperature in excess of 1500 DEG F, a cooler end portion operable at a temperature of less than 1250 DEG F, and an intermediate zone portion operable at between 1250 and 1500 DEG F. The blade with hot end portion is coated with a low creep-type coating which is resistant to high temperature corrosion and oxidation, the cooler end portion is coated with a ductile-type coating which is resistant to sulfide corrosion, and the intermediate portion coated with a mixture of the hot end coating and the cooler end coating.
