20100059573 | PROCESS OF FILLING OPENINGS IN A COMPONENT - A process for filling openings, including blind holes, through-holes, and cavities, in high temperature components. The process entails forming a powder mixture by mixing particles of at least a base alloy and a second alloy that contains a sufficient amount of a melting point depressant to have a lower melting temperature than the base alloy. The powder mixture is combined with a binder and compacted to form a compacted preform, which is then heated to remove the binder and form a rigid sintered preform. The sintered preform is produced, or optionally is further shaped, to have a cross-sectional shape and dimensions to achieve a clearance of up to 200 micrometers with the opening, after which the preform is placed in the opening and diffusion bonded within the opening to form a brazement comprising the particles of the base alloy dispersed in a matrix formed by the second alloy. | 03-11-2010 |
20110076151 | METHOD AND SYSTEM FOR FOCUSED ENERGY BRAZING - A method and system that includes generation of an energy beam. The energy beam may be generated from a focused energy source. Additionally, the energy beam may be directed towards a pre-sintered preform. The pre-sintered preform may be made of a braze material and may seal a hole that may be located in a turbine component. | 03-31-2011 |
20120231295 | METHOD OF FABRICATING A COMPONENT AND A COMPONENT - A method of fabricating a component and a component are disclosed. The method includes beam brazing a pre-sintered preform to the component to form a beam-brazed portion. The component includes a beam-brazed portion formed by a pre-sintered preform. | 09-13-2012 |
20130032577 | CLADDING SYSTEM AND METHOD FOR APPLYING A CLADDING TO A POWER GENERATION SYSTEM COMPONENT - A cladding system and method for applying a cladding to a power generation system component including a first weld bead, a second weld and a filler bead. The first weld is deposited on the surface with a first energy source and solidified to form a first weld bead. The second weld is deposited on the surface adjacent to the first weld bead with the first energy source, wherein depositing the second weld creates a surface depression between the first weld bead and second weld. The filler bead is simultaneously deposited in the surface depression with a second energy source while depositing the second weld bead. The second weld and the filler bead are solidified to form the cladding bead. | 02-07-2013 |
20130071250 | PROCESS OF WELDING A TURBINE BLADE, A PROCESS OF WELDING A NON-UNIFORM ARTICLE, AND A WELDED TURBINE BLADE - A process of welding an article and a welded turbine blade are disclosed. The process includes fusion welding over a primary symmetry line determined from a center of gravity on a first side of the article or blade and fusion welding over the primary symmetry line determined from the center of gravity on a second side of the article or blade. The fusion treating includes multiple fusion treatments. | 03-21-2013 |
20130095342 | BRAZING PROCESS, BRAZE ASSEMBLY, AND BRAZED ARTICLE - A brazing process, a braze assembly, and a brazed article are disclosed. The brazing process includes applying a braze material to an article within a vacuum chamber while the vacuum chamber is substantially evacuated. The braze assembly is capable of applying a braze material to an article within a vacuum chamber while the vacuum chamber is substantially evacuated. The brazed article is devoid of re-formed oxides. | 04-18-2013 |
20150056469 | METHOD OF FABRICATING A COMPONENT AND A MANUFACTURED COMPONENT - A method of fabricating a component and a fabricated component are disclosed. The method includes depositing a material to a component and manipulating the material to form a boundary region and a filler region for desired properties. The component includes the boundary region and the filler region, thereby having the desired properties. | 02-26-2015 |
20150104322 | THERMAL MANAGEMENT ARTICLE AND METHOD OF FORMING THE SAME, AND METHOD OF THERMAL MANAGEMENT OF A SUBSTRATE - A thermal management article, a method for forming a thermal management article and a thermal management method are disclosed. Forming a thermal management article includes forming a duct adapted to be inserted into a groove on the surface of a substrate, and attaching the duct to the groove so that the top outer surface of the duct is substantially flush with the surface of the substrate. Thermal management of a substrate includes transporting a fluid through the duct of a thermal management article to alter the temperature of the substrate. | 04-16-2015 |
