  • Patent number: 6378755
    Abstract: A joined structure includes a structure made of a structure metal, and a bonding element having a portion made of an open-cell solid ceramic foam. The open-cell solid ceramic foam has ceramic first-portion cell walls, and an intracellular volume therebetween that is filled with a bonding-element metal. A joint between the structure and the bonding element has an interdiffusion between the structure metal and the bonding element metal. A second structure may be joined to the first structure through the bonding element, using the same approach. The joints are formed by contacting the structure to the bonding element, and interdiffusing the metals on each side of the joint.

  • Patent number: 6291084
    Abstract: An environmental overlay coating for articles used in hostile thermal environments, such as turbine, combustor and augmentor components of a gas turbine engine. The overlay coating is predominantly beta-phase NiAl with limited alloying additions of zirconium and chromium. The overlay coating is useful as an environmental coating and as a bond coat that improves the spallation resistance of a thermal barrier coating (TBC) system.
