Abstract:
A method for filling cooling holes in a component of a gas turbine engine is disclosed. The component may include a plurality of first cooling holes penetrating the wall of the component. The method may comprise the steps of exposing the outer surface of the component, filling the plurality of first cooling holes of the component with a filling agent, curing the filling agent to block the passage of air through the cooling holes, and applying a thermal barrier coating over the surface of the component. The method may further include installing a second plurality of cooling holes, the second plurality of cooling holes penetrating the thermal barrier coating and the wall of the component and allow air to pass therethrough.

Abstract:
The invention provides a structure having a porous metal body firmly attached to a solid metal carrier as in figure 1. This composite structure is built up from a porous body (10) which is at least partially made of aluminium or an aluminium alloy and a solid metal carrier (20) made of aluminium or an aluminium alloy. There is also a formed in situ layer (30) obtainable by thermal spraying. This layer is bonded directly to at least a portion of said solid metal carrier material (20) and the porous body (10) is sintered to said layer (30) which is bonded to the solid metal carrier. Further, the present invention provides a method for firmly attaching a porous metal body to a solid metal carrier and the use of those structures in heat exchangers, electronic assemblies and heat sinks. More specifically, the invention provides a firmly bonded aluminium construction containing porous aluminium material and a solid aluminium carrier.

Abstract:
Method for fastening a component (4) to a structure (2) made from a refractory material. The invention is characterized in that the component (4) is positioned on the structure (2), and that a material layer (5) is then applied to the component (4) and the structure (2) by means of a surface coating method, thereby fastening the component (4) to the structure (2).
Abstract:
A plasma spray process for structuring self-cleaning glass surfaces and self-cleaning glass surfaces formed according to the process. Molten or heat softened particles of inorganic material are plasma spray deposited onto the surface of a substrate to create a micro-rough surface. If desired, a hydrophobic top coating layer can optionally be applied to the micro-rough surface. The micro-structured surface formed according to the invention is durable and self-cleaning.
