Patent number: 10103410Abstract: A method for joining a metal component to a ceramic component is presented. The method includes disposing a metallic barrier layer on a metallized portion of the ceramic component, and joining the metal component to the metallized portion of the ceramic component through the metallic barrier layer. The metallic barrier layer comprises nickel and a melting point depressant. The metallic barrier layer is disposed by a screen printing process, followed by sintering the layer at a temperature less than about 1000 degrees Celsius. A sealing structure including a joint between a ceramic component and a metal component is also presented.Type: GrantFiled: May 22, 2015Date of Patent: October 16, 2018Assignee: General Electric CompanyInventors: Sundeep Kumar, Mohamed Rahmane, Hongbo Cao, Darren Michael Stohr, Raghavendra Rao Adharapurapu, Ravikumar Hanumantha

Patent number: 9028997Abstract: The present application provides for ceramic collars and metal rings for active brazing in sodium-based thermal batteries. The ceramic collar may be an alpha-alumina collar configured for active brazing, and thereby sealing, to outer and inner Ni rings for use in NaMx cells. The portions of the alpha-alumina collar active brazed to the outer and inner Ni rings may be outwardly facing and include inwardly extending recesses. The portions of the outer and inner Ni rings active brazed to the outwardly facing portions of the collar may be inwardly facing. The alpha-alumina collar may include a greater coefficient of thermal expansion than each of the outer and inner Ni rings, and the alpha-alumina collar and outer and inner Ni rings may be configured such that a portion of the outer and inner Ni rings is deformed into the inwardly extending recesses of the alpha-alumina collar after active brazing thereof.Type: GrantFiled: December 28, 2012Date of Patent: May 12, 2015Assignee: General Electric CompanyInventors: Michael Colan Moscinski, Reza Sarrafi-Nour, Badri Narayan Ramamurthi, Mohandas Nayak, Darren Michael Stohr, Sundeep Kumar, Mohamed Rahmane, Arunabh Basak, Raghavendra Rao Adharapurapu
