Abstract: La presente invencion describe un metodo para reparar componentes formados de un material de superaleacion que comprende las etapas de proporcionar un componente formado de un material de superaleacion que tiene un defecto que se va a reparar y depositar un material de reparacion sobre una superficie del componente usando un gas portador no oxidante de modo que el material de reparacion se deforma plasticamente y se une a la superficie con el impacto con la superficie y por medio de esto cubre el defecto.

Abstract: A process for applying a coating to a substrate 10 comprising the steps of providing metal particles having a size up to 50 microns and passing the metal particles through a spray nozzle 20 at a speed sufficient to plastically deform them on the substrate. The metal particles preferably have a size of between 5-50 microns, and may be chosen from copper alloy, aluminium alloy or nickel alloy particles. The particles are preferably fed to the nozzle using a carrier gas of helium, nitrogen or a mixture of both. The substrate is preferably a stainless steel manifold for a rocket engine, and the coating is applied to at least one of its outer surface 26 or its inner surface 24. The nozzle may deposit a layer 28 between 0.025 - 0.076 mm thick per pass, and the total thickness of the layer may be greater than 1.27mm.

Abstract: The application of a coating material on a substrate (10) comprises: (a) providing some particles of metal powder with a size in a range from that sufficient to avoid being swept from the substrate due to a layer of shock waves or shock front up to 50 microns; (b) forming a deposition layer (28) on at least one surface of the substrate by passing the particles of metal powder across a spray nozzle (20) at a speed sufficient to plastically deform the particles of metal powder on the surface. An Independent claim is also included for the manifold of a rocket engine having a deposit of copper containing material deposited on at least one surface by this method.

Abstract: A process is provided for forming a deposit layer on a substrate, in particular forming a copper or copper alloy deposit layer on at least one of an inner surface and/or an outer surface of a metal alloy manifold used in a rocket engine. The process comprises the steps of providing metal powder particles having a size in the range of from a size sufficient to avoid getting swept away from the substrate due to a bow shock layer to up to 50 microns and forming a deposit layer on at least one surface of the substrate by passing the metal powder particles through a spray nozzle at a speed sufficient to plastically deform the metal powder particles on the at least one surface.
