| 20110070119 | MANUFACTURE OF COMPOSITE COMPONENTS BY POWDER METALLURGY - A method for preparing an article is disclosed. The method comprises compacting a mixture of a first pre-alloyed powder and a lubricant to thereby form a green part having a green strength sufficient to permit mechanical handling; applying a slurry to a surface of the green part to thereby form a slurry coated green part, wherein the slurry comprises a second pre-alloyed powder, a binder, and a solvent; and heating the coated green part to a temperature below a solidus temperature of the first pre-alloyed powder and between a solidus temperature and a liquidus temperature of the second pre-alloyed powder to thereby solid state sinter the first pre-alloyed powder into a sintered core and to liquid state sinter the second pre-alloyed powder into a continuous alloy coating over the sintered core. | 03-24-2011 |
| 20110067796 | SLURRY-BASED MANUFACTURE OF THIN WALL METAL COMPONENTS - A method for preparing a metal-based part, the method comprising applying a slurry to a surface of a temporary substrate to thereby form a slurry-coated temporary substrate, wherein the slurry comprises a Co-, Ni-, or Fe-based metal-based material, a binder, and a solvent; drying the slurry-coated temporary substrate to remove the solvent and to thereby form a coating layer having green strength; heating the coating layer to remove the binder; heating the coating layer to sinter the metal-based material into a continuous metal alloy layer; and separating the substrate from the coating layer. A powder metallurgy preform comprising a powder metallurgy green coating on a preform substrate. | 03-24-2011 |
| 20100316883 | SPALLATION-RESISTANT MULTILAYER THERMAL SPRAY METAL COATINGS - A wear- and corrosion-resistance coating over a metal substrate having a first-layer carbide material, a second metal coating layer over the first metal coating layer, and a surface metal coating layer over the second metal coating layer; and thermal spray method for applying the coating. | 12-16-2010 |
| 20100209286 | WELDABLE, CRACK-RESISTANT CO-BASED ALLOY, OVERLAY METHOD, AND COMPONENTS - A wear- and corrosion-resistant alloy, and related application method, where the alloy has by approximate weight %, C 0.12-0.7, Cr 20-30, Mo 7-15, Ni 1-4, and Co balance, wherein the alloy further contains one or more carbide-former elements from the group consisting of Ti, Zr, Hf, V, Nb, and Ta in a cumulative concentration to stoichiometrically offset between about 30% and about 90% of the C in the alloy. | 08-19-2010 |
| 20090032501 | ABRASION-RESISTANT WELD OVERLAY - A material blend for deposition of an abrasion-resistant overlay onto a metal substrate comprising a first metal particle component, a second metal particle component, and a carbide particle component and a method for the application thereof, wherein the overlay process conditions and the homogeneity of tungsten carbide distribution in the overlay are improved. | 02-05-2009 |
