In a method for repairing a coated article, the article has: a ceramic matrix composite (CMC) substrate; and a coating system having a plurality of layers. A damage site at least partially penetrates at least one of the layers. The method includes: applying a slurry of a repair material to the damage site for repairing a first of the penetrated layers; and after the applying, heating the repair material with a plasma torch.

Coating repair for ceramic matrix composite (CMC) substrates

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.

Article having variable composition coating

A flowpath component includes a body having at least one internal cooling passage. The internal cooling passage is defined by a surface layer including a first material, and an interior layer comprising a second material. The second material is distinct from the first material. The surface layer and the internal layer are additively manufactured as a single unitary structure.

Additively manufactured component for a gas powered turbine

A gaspath component includes a body having at least one internal cooling passage and a metering feature integral to the internal cooling passage. The metering feature and the body are a unitary structure.

A coated article has: a metallic substrate (); a bondcoat (); and a thermal barrier coating (TBC) (). The bondcoat has a first layer () and a second layer (), the first layer having a lower Cr content than the second layer.

Spallation-resistant thermal barrier coating

The present invention relates to an overlay coating which has improved strength properties. The overlay coating comprises a deposited layer of MCrAlY material containing discrete nitride particles therein. The nitride particles are present in a volume fraction in the range of 0.1% to 15.0% and have a particle size in the range of from 0.1 microns to 10.0 microns. The coating may also have oxide particles dispersed therein.
