Abstract: Ion-enhanced physical vapor deposition is augmented by sputtering to depos it multi-component materials. The process may be used to deposit coatings and repair material on Ti alloy turbine engine parts. The physical vapor deposition may be ion- enhanced electron beam physical vapor deposition.

Abstract: Clip Attachment The segmented wall of the float-wall combustor liner for a gas turbine engine is retained by a clip secured to a post extending radially from the outer wall through an opening in the segmented wall. The clip serves to load the walls radially and has fail-safe features preventing inadvertent dislodging.

Abstract: Physical vapor deposition is utilized to deposit repair material on Ti alloy turbine components. In a preferred embodiment, a damaged area (30) of an airfoil leading edge is machined to produce a base surface (50), and a backing element (52) is attached to the airfoil (26) to receive the repair material which can subsequently be machined to the appropriate profile.

Abstract: A method for depositing a first material on a substrate (108) includes providing the substrate (108) in a deposition chamber. A molten body (164) is formed between the substrate and a source of the first material by melting one or more second materials. A flow of the first material is passed through the molten body (164) and from the molten body (164) to the substrate (108) as a vapor flow. An essentially non-expending portion of the molten body comprises an alloy having a melting temperature below a melting temperature of the first material.

Abstract: An apparatus for microplasma spray coating a portion of a turbine vane (72) without masking includes a microplasma gun (12) with an anode (16), cathode (18), and an arc generator for generating an electric arc between the anode (16) and cathode (18). An arc gas emitter injects gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream (21). A powder injector (22) injects powdered material into a plasma stream (21). A localized area of the turbine vane (72) is coated with the powdered material (34) without having to mask the turbine vane (72).

Abstract: A method for renewal of turbine part made of titanium alloy that has lost material from place of destruction is performed through fixation of element of support with first surface to part. Element of support is placed in such way that first part of first surface is placed along the part and second part of first surface is placed near the place of destruction, material based on Ti is deposited through deposition from vapor in place of loss of material in such way that deposited material based on Ti is build-in on part and second part of first surface.

Abstract: An investment casting pattern is formed by installing a first core (20) to a first element (60) of a molding die (58) to leave a first portion (24) of the first core (20) protruding from the first element (60). After the installing, the first element (60) is assembled with a feed core (70) and a second element (62) of the molding die (58) so that the first portion (24) contacts the feed core (70) and is flexed. A material (92) is molded at least partially over the first core (20) and feed core (70).
