    Abstract: The present disclosure relates to a first seal for an aircraft blade outer air seal (“BOAS”) comprising a first portion comprising a first channel and a second channel, and a second portion comprising a first projection and a second projection, wherein the first projection slidably couples to the first channel and the second projection slidably couples to the second channel. The first portion and/or the second portion may be coated with a low friction substance. The first portion may be coupled to a vane support and/or a BOAS, and the second portion may be coupled to a first OAS support. The first seal may enable a radial translation of the BOAS in response to an aircraft maneuver.

    Abstract: Erosion- and impact-resistant ceramic coatings suitable for protecting surfaces subjected to collisions with particles, including nominally round particles that typically inflict impact damage and more aggressive irregular-shaped particles that typically inflict erosion damage. The ceramic coating is formed to have one of three compositions: at least one layer of titanium aluminum nitride (TiAlN) having a thickness of about 25 to about 100 micrometers; multiple layers of chromium nitride (CrN) and TiAlN, each layer having a thickness of about 0.2 to about 1.0 micrometers to yield a total coating thickness of at least about 3 micrometers; and at least one layer of titanium silicon carbonitride (TiSiCN) having a thickness of about 15 to about 100 micrometers. The ceramic coating preferably has a total coating thickness of up to about 100 micrometers, and is deposited by a physical vapor deposition process to have a columnar and/or dense microstructure.

    Abstract: A method of simultaneously applying three different diffusion aluminide coatings to a metal part with an external surface and internal passageways includes first placing the part in an enclosed retort. Areas of the part are then coated with aluminum containing slurry for a first diffusion aluminide coating. Interior walls of the retort are then coated with a vapor source slurry for a second vapor phase aluminide coating on the surface of the part. Areas on the surface of the part not requiring coating are coated with masking materials. A closed chamber inside the retort containing source material for a third vapor phase diffusion aluminide coating for the internal passageways is then attached to the internal passageways. The retort is then placed in a furnace under a protective atmosphere and subjected to a diffusion heat treat to coat the external surfaces and internal passageways with the three different aluminide coatings.
