20140305548 | CARBO-NITRIDING PROCESS FOR MARTENSITIC STAINLESS STEEL AND STAINLESS STEEL ARTICLE HAVING IMPROVED CORROSION RESISTANCE - A method for producing a case-hardened martensitic stainless steel article includes: providing an article comprised, at least in part, of a martensitic stainless steel, carburizing the article within a temperature range of 1625° F.-1680° F. (885° C.-916° C.), and then carbo-nitriding the article within a temperature range of 1575° F.-1625° F. (857° C.-885° C.). An article, such as a bearing ring, comprising such a case-hardened martensitic stainless steel is also disclosed. | 10-16-2014 |
20140264684 | PHOTOCONDUCTIVE SEMICONDUCTOR SWITCH - A photoconductive semiconductor switch comprising a photoconductive GaAs substrate having a pair of spaced metal contacts on a surface thereof, the spaced metal contacts opposite ends of a switching gap, the switching gap having a plurality of lateral current flow preventing channels therein, the channels being formed by ion implantation of the GaAs substrate in the channels. | 09-18-2014 |
20140130613 | AUTOMATED HIGH SPEED METALLOGRAPHIC SYSTEM - An metallographic system comprising a programmable controller, a robotic arm, a specimen clamping or holding device, a sectioning saw, a mounting station, a polishing station, a specimen preparation station, and an analyzer for examining the specimen. | 05-15-2014 |
20120087826 | HIGH STRENGTH ALUMINUM CASTING ALLOY - The present invention discloses a high strength Al—Zn—Mg—Cu (7000 series) alloy that can be cast, the cast alloy having a tensile strength of at least 500 megapascals (MPa) and 4% elongation. The cast alloy composition can include about 5.5-9.0 weight percent (wt. %) of zinc, 2.0-3.5 wt. % of magnesium, 0.1-0.5 wt. % scandium, 0.05-0.20 wt. % zirconium, 0.5-3.0 wt. % copper, 0.10-0.45 wt. % manganese, 0.01-0.35 wt. % iron, 0.01-0.20 wt. % silicon with a balance of aluminum and possible casting impurities. The alloy also has good fluidity comparable to high silicon cast aluminum alloys and components can be manufactured using direct chill casting, sand casting, and/or sand casting under high pressure. | 04-12-2012 |
20090305459 | Methods of Splitting CdZnTe Layers from CdZnTe Substrates for the Growth of HgCdTe - Methods of producing CdZnTe (CZT) layers for the epitaxial growth of HgCdTe thereon include implanting ions into a CZT substrate at a low temperature to form a damaged layer underneath a CZT surface layer, bonding a wafer to the CZT substrate about the CZT surface layer using a bonding material, and, annealing the CZT substrate for a time sufficient to facilitate the splitting of the CZT substrate at the damaged layer from the CZT surface layer. | 12-10-2009 |
20080220256 | METHODS OF COATING CARBON/CARBON COMPOSITE STRUCTURES - Embodiments of a method of preparing a coated C/C composite structure comprises the steps of: providing a C/C composite structure; applying a silicon based composition over the C/C composite structure by physical vapor deposition; forming a first layer comprising silicon carbide over the C/C composite by annealing the silicon based composition and the C/C composite at an annealing temperature; and applying a second layer comprising boron over the first layer by physical vapor deposition. | 09-11-2008 |
