20100098964 | METHOD FOR THE PRODUCTION OF A COATING - The invention describes a process for the production of a coating ( | 04-22-2010 |
20100310895 | POLYCRYSTALLINE ALUMINUM THIN FILM AND OPTICAL RECORDING MEDIUM - A polycrystalline aluminum thin film is made of polycrystals of an alloy of aluminum. The polycrystalline aluminum thin film includes a first additive which is distributed with even concentration over an inside of each crystal grain and an interface of the crystal grain and a second additive which is distributed with higher concentration in the interface of the crystal grain than in the inside of the crystal grain. | 12-09-2010 |
20110008639 | METHOD OF PRODUCING A SINTER-HARDENED COMPONENT - The invention describes a method of producing a sinter-hardened component from a metallic powder containing chromium which is pre-alloyed in particular, comprising the steps of compacting the powder to form a green compact and then sintering the green compact in a reducing sintering atmosphere at a sintering temperature in excess of 1100° C. A gas containing carbon is added to the sintering atmosphere. | 01-13-2011 |
20120088115 | CORROSION PROTECTION WITH AL / ZN-BASED COATINGS - Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg | 04-12-2012 |
20120202087 | METHOD FOR TREATING A POROUS ARTICLE - A method of treating a porous work piece includes infiltrating a liquid metallic alloy into surface porosity of a work piece and isothermally solidifying the liquid metallic alloy to at least partially fill the surface porosity. | 08-09-2012 |
20130230734 | POROUS IMPLANT MATERIAL - Porous implant material having a plurality of metal bodies having different porosity rates which are bonded with each other at bonded-boundary surface F parallel to a first direction, wherein: a bonded body of the metal bodies has an entire porosity rate of 50% to 92%; the metal body having higher porosity rate is a porous metal body having a three-dimensional network formed from a continuous skeleton in which a plurality of pores are interconnected; the metal body having lower porosity rate has a porosity rate of 0 to 50% and an area-occupation rate of 0.5% to 50% in a cross-section surface orthogonal to an axial direction which agrees with the first direction along the bonded-boundary surface; and a compressive strength compressing in a direction parallel to the bonded-boundary surface is 1.4 times to 10 times of a compressive strength compressing in a direction orthogonal to the bonded-boundary surface. | 09-05-2013 |
20130344347 | PROCESS FOR LOCAL REPAIR OF A DAMAGED THERMOMECHANICAL PART AND PART THUS PRODUCED, IN PARTICULAR A TURBINE PART - A process and device in production of precise three-dimensional sinters of a shape substantially close to that of an original part, using flash sintering produced by spark plasma sintering (SPS) technology. A mold is produced in a die of an enclosure for SPS flash sintering, the mold being shaped as an impression of the original part. The following are deposited in successive layers in the mold: a layer based on a superalloy powder, a metallic protection layer, and a thermal barrier layer. In a sintering, pressurization is initiated and a pulsed current passes through, producing a rapid rise in temperature in accordance with a flash sintering cycle whose temperature, pressure, and duration are regulated, with at least one temperature plateau and one pressure plateau. The layer of superalloy forms, by diffusion, during the sintering, a bonding continuum of material with the part to be repaired. | 12-26-2013 |
20140050937 | Sponge-Iron Alloying - A steel manufacturing process can include forming an iron oxide layer on a hot band during hot rolling; reducing the iron oxide layer on the hot band to form a sponge iron layer that includes pores; the sponge-iron layer having a thickness in a range of about 0.05 μm to about 1000 μm, about 0.1 μm to about 100 μm, or about 5 μm to about 25 μm; and depositing an alloying element into the pores of the sponge iron layer to form an impregnated sponge-iron layer. The process can further include annealing the impregnated sponge-iron layer to produce an iron alloy layer carried by the substrate. | 02-20-2014 |
