Patent number: 7008522Abstract: A method of locally repairing parts coated with a thermal barrier including a ceramic outer layer and a metal underlayer of alumina-forming alloy for protecting the substrate against oxidation and for bonding with the ceramic outer layer, includes: defining the zone for repair with a mechanical mask adapted to the shape of the part and the zone for repair; scouring the zone for repair so as to remove the ceramic, the alumina layer, and the damaged portions of the underlayer; supplying materials for repairing the underlayer to the repair zone by subjecting the partially-scoured part to metal deposition by use of an electrical current; and subjecting the part to a heat treatment in order to enable the added metals to diffuse into the remaining underlayer in the repair zone for repair and to enable a surface film of alumina to form. After the underlayer has been reconstituted, the zone for repair is again defined by a mechanical mask and a new ceramic layer is deposited thereon.Type: GrantFiled: July 11, 2002Date of Patent: March 7, 2006Assignee: Snecma Moteurs-Snecma ServicesInventors: Bruno Gilles François Boucard, Jean-Paul Fournes, Frédéric Yves Pierre Jacquot, Yann Philippe Jaslier, Jacques Louis Leger, André Hubert Louis Malie, Guillaume Roger Pierre Oberlaender, Catherine Marie-Hélène Richin

Patent number: 6432478Abstract: A ceramic heat barrier coating is deposited on a substrate so that the coating has a columnar growth pattern which is interrupted and repeated a number of times throughout its thickness by successive regermination of the ceramic deposit. The regermination is obtained by a vapor phase deposition process wherein a polluting gas is introduced intermittently during the deposition of the ceramic. The resulting ceramic coating has a lower thermal conductivity than conventional columnar ceramic coatings.Type: GrantFiled: January 12, 2001Date of Patent: August 13, 2002Assignee: Societe Nationale d'Etude et de Construction de Moteurs d'Aviation “Snecma” and Snecma ServicesInventors: Yann Philippe Jaslier, André Hubert Louis Malie, Jean-Pierre Julien Charles Huchin, Serge Alexandre Alperine, Romain Portal
