Patent number: 9607801Abstract: A structure and associated process for joining dissimilar materials to form various components of an x-ray tube is illustrated that utilizes one or more intermediate or interfacial filler material members positioned between the primary welding or mating surfaces of the base material components to be joined. The use of the interfacial or intermediate filler material preserves the multiple benefits of friction welding, as well as enabling the joining of highly dissimilar material components, decreasing the required joining temperature, and providing increased microstructural control of the resulting weld or joint.Type: GrantFiled: September 19, 2014Date of Patent: March 28, 2017Assignee: General Electric CompanyInventors: Ben David Poquette, Michael Scott Hebert, Kirk Alan Rogers, Michael Louis Szugye, Gregory Alan Steinlage, Donald Robert Allen

Patent number: 9500226Abstract: Various methods and systems are provided for providing coatings and textures to surfaces of a bearing assembly in an x-ray system to control the wettability of the surfaces when components of the bearing assembly rotate during operation of the x-ray system. A lubricant is disposed in a gap formed between a shaft and a sleeve of the bearing assembly such that textured and coated surfaces of the shaft and sleeve alter wetting properties between the lubricant and surfaces. The coatings and textures can be wetting or anti-wetting to further enhance control over the behavior of the lubricant.Type: GrantFiled: August 13, 2014Date of Patent: November 22, 2016Assignee: General Electric CompanyInventors: Ian Strider Hunt, Kenwood P.

Patent number: 7586233Abstract: Composite materials comprising ferroelastic ceramic particulates dispersed in a metal matrix are capable of vibration damping. When the ferroelastic ceramic particulates are subjected to stress, such as the cyclic stress experienced during vibration of the material, internal stresses in the ceramic cause the material to deform via twinning, domain rotation or domain motion thereby dissipating the vibrational energy. The ferroelastic ceramic particulates may also act as reinforcements to improve the mechanical properties of the composites. The composite materials may be used in various structural components in vehicles, aircraft, spacecraft, buildings and tools.Type: GrantFiled: October 23, 2006Date of Patent: September 8, 2009Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Jeffrey Patrick Schultz, Ted Ankomahene Asare, Ben David Poquette, Stephen Lynn Kampe
