Abstract: In an aspect, a method of forming a coating on a busbar comprises cold spraying a powder comprising a plurality of metal particles onto the busbar at a velocity sufficiently high to cause the plurality of metal particles to deform upon contact with the busbar thereby forming the coating on the busbar; wherein the plurality of metal particles comprises greater than or equal to 50 weight percent of at least one of nickel, tin, silver, zinc, or copper based on the total weight of the metal particles; and wherein the coating has an average thickness of greater than or equal to 10 micrometers. In another aspect, a coated busbar is formed by cold spraying.

Abstract: The present disclosure is related to homogeneous alloys comprising titanium and 9% to less than 20% by weight of tungsten, wherein the alloy has a yield strength of at least 120,000 psi and ductility of least 20% elongation; and with further alloying an ultimate tensile strength of at least 200,000 psi and useful ductility of at least 2% elongation; and with the addition of ceramic particulate reinforcements can exhibit an ultimate tensile strength of at least 180,000 psi. Products and metal matrix composites comprising such homogeneous alloys are also disclosed. The metal matrix composites further comprise a discontinuous reinforcement chosen from TiC, TiB2, or TiB, particles or combinations of such particles. Method of making such alloys and composites as well as products made from such alloys and composites are also disclosed.

Abstract: Disclosed herein is a scratch-resistant article for covering an object, such as a cellular phone, wherein the article comprises titanium metal or titanium alloy with grain size greater than 0.030 inch. Also disclosed is a method of producing such articles comprising thermally treating titanium in vacuum at a minimum temperature of 1900° F. for at least 5 minutes.

Abstract: Disclosed herein are extruded titanium metal matrix composites with enhanced ductility. Also disclosed is the extrusion at high extrusion ratio of titanium metal matrix composites produced by powder metal processes. The ductility and machinability of these titanium metal matrix composites extruded at high extrusion ratios combined with their wear resistance and excellent imaging characteristics makes these high extrusion ratio extruded titanium metal matrix composites useful as biological implants, including prosthetic devices. Also disclosed are articles such as orthopedic implants for knee, hip, spine or other biomedical devices, with enhanced properties, made from the disclosed extruded material.

Abstract: Disclosed herein are alpha-beta titanium alloys processed above the beta transus temperature yet that maintain a fine grain structure. Disclosed herein are articles comprising a titanium alloy body and a porous titanium material attached to the body, wherein the titanium alloy body has a grain size of less than or equal to 0.1 inch. Such articles may be useful as orthopedic implant devices, such as those for the knee, hip, or other prostheses. Also disclosed is a powder metal process for producing such articles, which includes consolidating powdered metals to full density by pressing, sintering and hot isostatic pressing. The shape can be further extruded to a mill product or forged to near net shape.

Abstract: Disclosed herein are titanium-tungsten alloys and composites wherein the tungsten comprises 0.5% to 40% by weight of the alloy. Also disclosed is a method of making such alloys and composites using powders of tungsten less then 3 ?m in size, such as 1 ?m or less. Also disclosed is a method of making the titanium alloy by powder metallurgy, and products made from such alloys or billets that may be cast, forged, or extruded. These methods of production can be used to make titanium alloys comprising other slow-diffusing beta stabilizers, such as but not limited to V, Nb, Mo, and Ta.

Abstract: Breaking and/or test strength of aramid fabrics are enhanced when finished with a fabric softener. Improvements of up to 50% over the corresponding untreated greige fabrics and up to 45% over the corresponding untreated dyed fabric are achieved without detracting from flame resistance of these fabrics.
