A method for depositing an electrically conductive metal onto at least one portion of the inner surface () of an internal cavity () of a waveguide () includes: preparing a suspension containing at least one liquid and at least one precursor of the electrically conductive metal in suspension in said at least one liquid; coating at least one portion of the inner surface () of the internal cavity () of the waveguide () with the suspension, and heat-treating at least said portion of the inner surface () of the internal cavity () of the waveguide () coated with the suspension. A method for manufacturing a metallized waveguide can implement this deposition method.

Method for brazing or refilling comprising the following steps:

Method for brazing or refilling a part with micro-interstices, and heat exchanger obtained with such a method

A method and a device are provided for removing surface oxides on nodules of a metal powder, before the nodules of the metal powder are used in an industrial process in which the nodules of the metal powder are assembled via a solid route or via a liquid route. In the method and the device, the surface oxides are stripped from the nodules of the metal powder by bringing the nodules of the metal powder into contact with vapour from at least one of: sublimation of a stripping solid material, and sublimation of the stripping solid material followed by a chemical transformation of a product of the sublimation.

Method allowing the removal of oxides present on the surface of nodules of a metal powder before using same in an industrial method

A metal matrix () for a heat exchanger (), comprising a stack of components (), in particular etched plates or corrugations (), separator sheets () and bars (), or a combination of the two types of stack, said components () being held relative to one another by layers of braze material (), thereby ensuring the mechanical integrity of the matrix, the matrix including fluid circulation passages () within it, each fluid circulation passage () having an inner wall provided to fully contain said fluid radially, characterized in that each inner wall is fully covered with a corrosion-resistant coating (). Preferred application to heat exchangers based on carbon steel or stainless steel.

Corrosion-resistant heat exchanger matrix and method of manufacturing such a matrix

Process for depositing a coating on a substrate having at least one cavity, comprising a step of mixing ground powders of an activating agent and a powder of the metal or of the alloy to be deposited on the substrate that were ground in step a) and a liquid so as to form a suspension, and a step of applying the suspension to the portion of the substrate to be coated.

Method for depositing a corrosion-protection coating from a suspension

Process for depositing a corrosion-protection coating on at least one portion of the surfaces of a metallic substrate having at least one cavity with an equivalent diameter e&#x3c;2 mm and a length/width ratio of greater than 150, using an aqueous suspension comprising powder of the metal to be deposited on the substrate combined with an agent for protecting the surface of the metal powder, a diluent, and at least one additive, the particles of the suspension each having an equivalent diameter d such that d&#x2264;e/10.

Method for depositing an anti-corrosion coating

Process for producing an element comprising a multilayer architecture, the layers of which comprise primary channels on their upper faces, said process comprising the following successive steps:
