Publication number: 20130323417Abstract: A method of forming a highly densified chemical matrix composite CMC from a preform of a matrix of a non-oxide ceramic and continuous ceramic fibers. An interface coating is added, followed by partially densifying the preform with a resin to increase the density of the preform using a polymer infiltration pyrolysis PIP) process one or more times. A chemical vapor infiltration (CVI) process is used to bring the CMC to a final desired density.Type: ApplicationFiled: March 26, 2013Publication date: December 5, 2013Applicant: United Technologies CorporationInventor: United Technologies Corporation

Publication number: 20130309399Abstract: A nickel oxide powder material that can restrain cracking of electrode due to oxidation expansion and peeling from a electrolyte and thus can decrease deterioration of the power generation characteristics, when used as an anode material for a solid oxide type fuel cell and its efficient production method, and the anode material for the solid oxide type fuel cell using the nickel oxide powder material. The nickel oxide powder material for an anode material constituting a solid oxide type fuel cell is characterized in that it is made up of a core particle (a) composed of a nickel oxide fine particle and a coating layer (b) including a zirconium hydroxide, which is formed on the surface of the core particle (a), as its main component, and that the zirconium content contained in the coating layer (b) is 0.001 to 0.01 g/m2 per surface area of the nickel oxide fine particle.Type: ApplicationFiled: July 30, 2013Publication date: November 21, 2013Applicant: SUMITOMO METAL MINING CO., LTD.Inventors: Norimichi Yonesato, Yasumasa Hattori, Hideyuki Yamashita, Tai Itou

Publication number: 20130295288Abstract: Carbon nanotube (CNT) arrays are attractive thermal interface materials with high compliance and conductance that can remain effective over a wide temperature range. Disclosed herein are CNT interface structures in which free CNT ends are bonded using palladium hexadecanethiolate Pd(SC16H35)2 to an opposing substrate (one-sided interface) or opposing CNT array (two-sided interface) to enhance contact conductance while maintaining a compliant joint. The palladium weld is mechanically stable at high temperatures. A transient photoacoustic (PA) method is used to measure the thermal resistance of the palladium bonded CNT interfaces. The interfaces were bonded at moderate pressures and then tested at 34 kPa using the PA technique. At an interface temperature of approximately 250° C., one-sided and two-sided palladium bonded interfaces achieved thermal resistances near 10 mm2 K/W and 5 mm2 K/W, respectively.Type: ApplicationFiled: July 10, 2013Publication date: November 7, 2013Inventors: Timothy S.
