A heat sink includes a plurality of layers being disposed substantially parallel with a surface of a heat source. The layers include a plurality of pin portions spaced apart from each other in a planar arrangement wherein the pin portions of the layers are stacked and bonded to form pin fins extending in a transverse direction relative to the heat source to sink heat. A compliant layer is disposed between the pin fins and a mechanical load. The compliant layer provides compliance such that the pin fins accommodate dimensional differences when interfacing with the heat source.

A braze gel includes a braze powder, a braze binder, and a viscosity reducer. The braze gel has a gel viscosity sufficiently low to permit dip coating of a component with the braze gel to apply a braze coating of the braze gel to the component. A brazing process includes applying the braze gel to a portion of a component. The brazing process also includes drying the braze gel to form a braze coating on the component to form a braze-coated component. A brazing article includes a component and a braze coating over a portion of the component. The component may have structural features having a spacing of less than about 5 mm and a depth of at least about 1 mm, which may be honeycomb cells. The component may be a turbine component.

The present disclosure relates to a method for producing a final metal part for a nacelle of a turbojet. The method includes brazing at least two parts, one being an inner part having an inner surface and the other being an outer part having an outer surface. The method further includes a step of heating the outer surface of the outer part using an external heating means, and a step of heating the inner surface of the inner part using an internal heating means.

The disclosure relates to a method for producing a diffusion blocking layer including aluminum oxide on a metal plate, which consists of a base material containing at least iron (Fe) and chromium (Cr). The aluminum used for forming the aluminum oxide is contained in the base material. A layer made of titanium dioxide serves as an oxygen contributor for the oxidation of the aluminum to a-aluminum oxide. The disclosure further relates to an integration of the method into the production of an exhaust gas treatment unit, where the exhaust gas treatment unit has a honeycomb body and a housing wither of which is formed with a metal plate having a base material that contains at least iron (Fe) and chromium (Cr). According to the disclosure, the metal plate includes a surface layer at least in one sub-region including at least aluminum oxide and titanium oxide.

The present invention provides a high Al-content steel sheet having an excellent workability and a method of production of the same at a low cost by mass production, a high Al-content metal foil and a method of production of the same, and a metal substrate using a high Al-content metal foil, that is, a high Al-content steel sheet having an Al content of 6.5 mass % to 10 mass %, the high Al-content steel sheet characterized by having one or both of a {222} plane integration of an -Fe crystal with respect to the surface of the steel sheet of 60% to 95% or a {200} plane integration of 0.01% to 15% and a method of production of the same, a high Al-content metal foil and a method of production of the same, and a metal substrate using a high Al-content metal foil.

A method for creating metallic sandwich structures that includes providing at least two face sheets; providing at least two core sheets; orienting the core sheets relative to one another in a predetermined manner; and using indirect resistance roll brazing to join the core sheets to the face sheets to create a sandwich structure.
