Abstract: A method for depositing an aluminizing coating onto a substrate. The method includes: (a) depositing a layer, containing platinum and at least 35% of nickel, onto a surface of the substrate; and (b) depositing an aluminum coating onto the layer.

Abstract: The invention relates to a method of fabricating a bath of electrolyte for plating a platinum-based metal underlayer on a metallic substrate, comprising: a) providing a first system having ligands and amine functional groups, the first system being constituted by an aqueous solution of an amino ligand comprising at least one compound X—(NH2)n, where X belongs to the group constituted by (CH3, CH3—CH2, CH3—(CH2)m), or NH3 or an xP?(NH4)+p salt where x is an acid radical belonging to the group constituted by (PO43?, HPO42?, H2PO4?, HPO42?and H2PO4?, SO42?, HSO4?, H2SO4, HSO4?, and H2SO4, CH3COO?, CH3COOH, and CH3COO?), or H2SO4, or CH3COOH, and where n, m, and p are non-zero integers; b) providing a second system forming a buffer system; c) providing a third system providing a metallic salt, and constituted by an aqueous solution of platinum; d) providing a fourth system suitable for imparting the conduction property to the medium; and e) mixing together the four systems so as to obtain the electrolyte bath.

Abstract: A removable mask for a platform or a nozzle sector of a turbine engine blade, the blade or sector configured to be covered in an electrolytic deposit, the mask including a mechanism to engage on the platform and a mechanism to cover outer surfaces of the platform that are not to be covered by the electrolytic deposit.

Abstract: Arranged in a bath contained in a tank are respectively an anodic electrode and a cathodic electrode, which are connected to an electric current generator. The cathodic electrode can be composed of a plurality of individual test specimens suitable for being immersed in the metal bath, and the device additionally includes a controllable electric power supply unit for the individual cathodic test specimens, which is connected to the current generator and includes a mechanism for controlling the current passing through the cathodic test specimens so that a given current flows in each of them.
