The present invention relates to a coating material for the production of an anti-corrosion and/or adhesion promoter layer, which material comprises metal powder and a phosphate-ion-containing solution as the binder, the metal powder being at least partially coated with Si or Si alloys or the binder consisting of phosphoric acid and metal phosphates and being substantially free of chromates. The invention further relates to a method for producing an anti-corrosion and/or adhesion promoter layer, comprising the following steps: Providing a coating material, such as indicated above, applying the coating material to a component surface on which the anti-corrosion and/or adhesion promoter layer is to be created, and drying and/or hardening by way of a heat treatment at a first temperature.

A highly efficient gas turbine engine is provided. The fan of the gas turbine engine is driven from a turbine via a gearbox, such that the fan has a lower rotational speed than the driving turbine, thereby providing efficiency gains. The efficient fan system is mated to a core that has low cooling flow requirements and/or high temperature capability, and which may have particularly low mass for a given power.

A turbine shroud assembly adapted for use in a gas turbine engine includes a blade track segment and a carrier. The blade track segment includes a runner that extends circumferentially partway around a central axis and an attachment post that extends radially from the runner. The carrier is coupled with the attachment post to support the blade track segment relative to the central axis.

The present invention relates to a fire resistant fan casing for a gas turbine engine. The casing has a projection such as a reinforcing rib or a mounting pad. The projection comprises at least one shell portion formed of a fiber/plastic composite material encasing a core of fire resistant material such as a metallic material or a ceramic matrix composite material.

An article with an erosion protection layer. The erosion protection layer may include metal, intermetallic compound, ceramic or glass nanocellular foam particles or monolithic sheets. The particles are dispersed in a polymeric matrix and the monolithic sheets are infiltrated with polymeric material. The nanocellular foam ligaments have submicron cross-sectional diameters.

A modified organic matrix composite having a thermal barrier coating comprising a substrate comprising an organic matrix composite; a roughness layer coupled to the substrate; a bonding layer coupled to the roughness layer opposite the substrate; and a thermal barrier coating coupled to the bonding layer opposite the roughness layer.

A method of making a light weight housing for an internal component is provided. The method including the steps of: forming a first metallic foam core into a desired configuration; forming a second metallic foam core into a desired configuration; inserting an internal component into the first metallic foam core; placing the second metallic foam adjacent to the first metallic core in order to secure the internal component between the first metallic foam core and the second metallic foam core; and applying an external metallic shell to an exterior surface of the first metallic foam core and the second metallic foam core.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; inserting a pre-machined component into an opening in the metallic foam core; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration and after the pre-machined component has been inserted into the metallic foam core; introducing an acid into an internal cavity defined by the external metallic shell; dissolving the metallic foam core; and removing the dissolved metallic foam core from the internal cavity, wherein the component and the external metallic shell are resistant to the acid.

A compressor with negative coefficient of thermal expansion case material comprising a rotor having blades with tips, the case including an inner case comprising a negative coefficient of thermal expansion material, and a tip clearance located between the tips and the inner case; wherein the tip clearance is maintained responsive to a flow of air over the negative coefficient of thermal expansion material.

An airfoil assembly includes a support carrier and an airfoil unit that includes a platform, an airfoil, and a mount. The platform defines a boundary of a gas path of the airfoil assembly. The airfoil extends away from platform and the mount extends away from the platform opposite the airfoil. The support carrier is coupled with the airfoil unit and engages the mount.
