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.

Abstract: 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.

Abstract: Aspects of the disclosure are directed to a servicing of an airfoil of an aircraft engine. A first portion of a first bondcoat layer may be removed from the airfoil while leaving a second portion of the first bondcoat layer intact on the airfoil. A second bondcoat layer may be applied to the airfoil using a coating technique subsequent to the removal of the first portion of the first bondcoat layer.

Abstract translation: 本公开的方面涉及飞机发动机的翼型件的维修。 第一粘合涂层的第一部分可以从机翼上去除，同时在翼型件上完整地留下第一粘结涂层的第二部分。 第二粘合涂层可以在除去第一粘结涂层的第一部分之后使用涂覆技术施加到翼型件。
