Abstract: A friction surfacing apparatus and method for depositing one or more metals, metal alloys, or other materials is disclosed. The friction surfacing apparatus includes a pin tool holder, a non-consumable shoulder having an inside diameter and an outside diameter, the inside diameter terminating at an end wall and includes an angled side wall that forms a substantially frustoconical opening at one end, and a consumable pin tool coupled to the pin tool holder and at least partially protruding from the end wall of the shoulder. The shoulder is maintained at a predetermined distance from a surface of a workpiece such that the consumable pin tool deposits pin tool material onto the surface of the workpiece during a friction surfacing operation.

Abstract: An article is presented where the article comprises an alloy having a minor phase dispersed within a matrix phase and a plurality of substantially equiaxed grains. The article further comprises a continuous gradient in grain size from a first grain size at an outer surface of the article to a second grain size at an inner portion of the article, wherein the first grain size is less than the second grain size. Methods for forming the article using high deformation processing are also presented, where the processing includes extruding the feedstock material through a die having a twist channel configured to apply a torsional strain to the feedstock material as it passes through the die to form an extruded billet.

Abstract: A coating process and TBC system suitable for protecting the surface of a component subjected to a hostile thermal environment. The TBC system has a first layer with a columnar microstructure, and a second layer on the first layer and with a microstructure characterized by irregular flattened grains. According to one aspect, the first layer is present and the second layer is not present on a first surface portion of the component, and the first and second layers are both present on a second surface portion of the component. According to another aspect, the first and second layers contain the same base ceramic compound.

Abstract: An erosion resistant protective structure for a turbine engine component comprises a shape memory alloy. The shape memory alloy includes nickel-titanium based alloys, indium-titanium based alloys, nickel-aluminum based alloys, nickel-gallium based alloys, copper based alloys, gold-cadmium based alloys, iron-platinum based alloys, iron-palladium based alloys, silver-cadmium based alloys, indium-cadmium based alloys, manganese-copper based alloys, ruthenium-niobium based alloys, ruthenium-tantalum based alloys, titanium based alloys, iron-based alloys, or combinations comprising at least one of the foregoing alloys. Also, disclosed herein are methods for forming the shape memory alloy onto turbine component.

Abstract: A pitch mark repair tool that includes a base with a push ledge at one end and a location for a thumb positioned at least one third way across the base from the push ledge. Preferably the location for the thumb is an indentation or ridged area, the center of which is at least half way across the base from the push ledge. The tool also includes a single prong extending from the push ledge or from a portion of the base adjacent the push ledge. The tool can be made from plastic, wood, metal, or any other suitable material. The base can be shaped to have a flat profile when viewed side-on or to have a profile of a corporate logo (e.g., the Nike® “swoosh”) when viewed side-on. Other shapes are possible. Also, methods of using the pitch mark repair tool.

Abstract: A pitch mark repair tool that includes a base with a push ledge and a single prong extending from the push ledge or from a portion of the base adjacent the push ledge. Preferably, the push ledge is a hilt that acts as a thumb guard. The base preferably includes a location for a thumb positioned away from the push ledge. The location for the thumb can be an indentation or ridged area. The base can be shaped to have a flat profile or to have a profile of a corporate logo (e.g., the Nike® “swoosh”) when viewed side-on. Other shapes are possible. Also, methods of using the pitch mark repair tool.

Abstract: The invention relates to oxide ceramic fiber composite materials that, e.g., according to the invention, are used in energy conversion installations. The present invention discloses a fundamentally new concept for the previously incompatible requirements of improved brittle fracture behavior to secure thermal shock stability and damage tolerance in the temperature range of <1000° C. and of mechanical high-temperature stability to guarantee long-term form stability (creep resistance) of components.

Abstract: A linerless label roll includes a web wound along a running axis, and having a series of index marks spaced longitudinally apart. A series of adhesive patches runs along the web, with differently sized adhesive-free zones therebetween in register with the index marks.

Abstract: A foldform label laminate includes a web having first and second bands laminated together along a longitudinal running axis by complementary patterns of release and adhesive disposed therebetween. The patterns of release and adhesive repeat along the running axis to define a series of repeating laminated sheets. The second band has a corresponding label disposed in each of the sheets. Each of the labels is removable from atop the first band, with the adhesive remaining on the label, and the release remaining on the first band.

Abstract: A label roll includes a web having front and back surfaces wound in a roll. The back surface includes adhesive patches aligned in a column along the running axis of the web. The front surface includes a release strip behind the column of patches and laminated thereto in successive layers in the roll.

Abstract: An economical process for the manufacture of a polycrystalline, sintered, ceramic abrasive from a powder raw material is described, which process is characterized by the following process steps: preparation of a slip largely free from polymerizing and/or coagulating additives from the powder raw material; pressureless shallow casting of the slip in a vessel; degassing, drying and crushing of the cast sheet to obtain a fabricated material and sintering of the fabricated material to create the abrasive. This process can be used to manufacture an abrasive that permits extremely high grinding performance due to its extraordinary density and structural integrity.

Abstract: The invention relates to the field of ceramics and concerns sintered Al.s2 O.sub.3 compositions produced from corundum powder and also methods for the use of the invented compositions as medical implants or tool material. To produce such materials, an initially unsintered precursor having a relative density of .rho..gtoreq.55% is produced from .alpha.-Al.sub.2 O.sub.3 powder having defined properties using at least two different dispersing methods, this precursor is subsequently subjected to heat treatment and sintering.
