Patent number: 9464363Abstract: A method for repairing a blade forming a cathode and having a surface to be coated defining a critical area, utilizing an anode, an electrolyte bath including insoluble particles, and a mounting on which the blade is mounted in a working position relative to a reference wall. The mounting is placed in the bath, and the particles and the metal of the anode are co-deposited to form the coating on the surface to be coated. The anode is typically placed facing the critical area and the mounting includes a mechanism for monitoring current lines to obtain a coating with a relatively constant, predetermined thickness for the critical area, that gradually falls to a value of substantially zero along edges of the coating.Type: GrantFiled: December 28, 2010Date of Patent: October 11, 2016Assignees: SNECMA, PRAXAIR SURFACE TECHNOLOGIES INC.Inventors: Justine Menuey, Frederic Braillard, John Foster, Stephen Owens, Alan Taylor, Martin Chatterney

Patent number: 8449677Abstract: The invention relates to the field of methods of depositing a material on a substrate. It relates to a method of depositing, onto a substrate, a material that acts as a thermal barrier and that prior to deposition is in powder form. The powder is introduced into the plasma jet of a first plasma torch and into the plasma jet of at least one second plasma torch, the first plasma torch and at least the second plasma torch being disposed in an enclosure and oriented in such a manner that their plasma jets cross, so as to create a resultant plasma jet in which the powder is vaporized, the substrate being placed on the axis of the resultant plasma jet.Type: GrantFiled: June 16, 2010Date of Patent: May 28, 2013Assignee: SNECMAInventors: Frederic Braillard, Justine Menuey, Elise Nogues, Aurelien Tricoire, Michel Vardelle

Patent number: 7816307Abstract: The invention relates to a novel self-lubricating solid material; to a method of preparing such a material from a powder mixture; to said powder mixture; and to mechanical parts made of said novel material. Said powder mixture comprises a powder of a metal alloy that is a precursor for the matrix of said material, particles of a first solid lubricant such as CeF3 that are for insertion in said matrix without reacting with said metal alloy, and particles of a second solid lubricant such as WS2 or MoS2 for reacting with a component of said metal alloy during sintering of the powder to form a lubricating phase. Said material can be used for fabricating a bushing that is to receive a root of a variable-pitch vane of an airplane turbojet compressor.Type: GrantFiled: January 11, 2006Date of Patent: October 19, 2010Assignees: SNECMA, SNECMA ServicesInventors: Frederic Braillard, Christelle Foucher, Philippe Perruchaut
