  • Patent number: 8765226
    Abstract: A patterned layer over a wafer is produced by depositing a print-patterned mask structure. Energized particles of a target material are deposited over the wafer and the print-patterned mask such that particles of said target material incident on the mask structure enter the mask structure body and minimally accumulate, if at all, on the surface of the mask structure, and otherwise the particles of target material accumulate as a generally uniform layer over the wafer. The print-patterned mask structure, including particles of target material therein, is removed leaving the generally uniform layer of target material as a patterned layer over the wafer.

  • Publication number: 20140161984
    Abstract: A class of nickel based alloys having a fine grain structure resistant to stress corrosion cracking, and methods of alloy design to produce further alloys within the class are presented. The alloys act as suitable welding materials in similar applications to that of Alloy 622. The fine-grained structure of these novel alloys may also be advantageous for other reasons as well such as wear, impact, abrasion, corrosion, etc. These alloys have similar phases to Alloy 622 in that they are composed primarily of austenitic nickel, however the phase morphology is a much finer grained structure opposed to the long dendritic grains common to Alloy 622 when it is subject to cooling rates from a liquid state inherent to the welding process.

  • Patent number: 8747956
    Abstract: Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. A stream of molten alloy and/or a series of droplets of molten alloy are produced. The molten alloy is atomized to produce electrically-charged particles of the molten alloy by impinging electrons on the stream of molten alloy and/or the series of droplets of molten alloy. The electrically-charged molten alloy particles are accelerated with at least one of an electrostatic field and an electromagnetic field. The accelerating molten alloy particles are cooled to a temperature that is less than a solidus temperature of the molten alloy particles so that the molten alloy particles solidify while accelerating. The solid alloy particles are impacted onto a substrate and the impacting particles deform and metallurgically bond to the substrate to produce a solid alloy preform.

  • Patent number: 8647751
    Abstract: During engine operation, valve retainers and valve springs are constantly rubbing and impacting each other resulting in heat and wear. The purpose of this invention is to provide a surface coating onto the valve retainer to reduce the friction with the valve spring and thus improve durability. Specifically, this invention teaches a method to thermally apply coatings to the surface of the valve retainer. Although typically fabricated from steel, the usage of lighter weight titanium valve retainers is increasing for high performance, or racing engines. The reduced mass allows valves to move more readily and requires less spring pressure to operate, producing more power and a faster revving engine, however titanium is typically not as wear resistant as the steel it replaces. In one embodiment, a porous molybdenum or other oleophilic metal is applied to the surface of the valve retainer. In another embodiment, hard coatings of cermets, carbides, and super alloys are applied as coatings to valve retainers.
