Abstract
A coated article includes a substrate and an MCrAlY coating supported on the substrate. The M includes at least one of nickel, cobalt, and iron, Cr is chromium, Al is aluminum, and Y is yttrium. The composition of the MCrAlY coating varies in an amount of at least one of Cr, Al, and Y by location on the substrate with respect to localized property requirements. In one example, the coated article is an article of a gas turbine engine.
Claims18
A coated article comprising:
- a substrate;
- and
- an MCrAlY coating supported on the substrate, where the M includes at least one of nickel, cobalt, and iron, Cr is chromium, Al is aluminum, and Y is yttrium, the composition of the MCrAlY coating varying in an amount of at least one of Cr, Al, and Y by lateral location on the substrate and with respect to localized property requirements of the coated article, wherein the coating is functionally graded between locations that vary in composition.
A gas turbine engine comprising:
- an article having a substrate and an MCrAlY coating supported on the substrate, where the M includes at least one of nickel, cobalt, and iron, Cr is chromium, Al is aluminum, and Y is yttrium, the composition of the MCrAlY coating varying in at least one of Cr, Al, and Y by lateral location on the substrate with respect to localized property requirements of the coated article, wherein the coating is functionally graded between locations that vary in composition.
