摘要:
A method for depositing a powder metal onto a surface of the substrate and a substrate with conductive elements provided on a surface of the substrate are disclosed. The conductive elements are formed by cold spray depositing at least one layer of powder metal onto the surface of the substrate to form at least one conductive element on the surface of the article.
摘要:
A titanium aluminide application process and article with a titanium aluminide surface are disclosed. The process includes cold spraying titanium aluminide onto an article within a treatment region to form a titanium aluminide surface. The titanium aluminide surface includes a refined gamma/alpha2 structure and/or the titanium aluminide is cold sprayed from a solid feedstock of a pre-alloyed powder.
摘要:
A system or method for applying a protective environmental coating for a gas turbine component. The coating includes a bond layer applied to a substrate comprised of a ceramic matrix composite material and environmental barrier coating layers. The first environmental barrier coating layer is bonded to the substrate by the bond layer. The bond layer comprises silicon and particles consisting of particles of Lanthanum or Cerium.
摘要:
A method for brazing a component in a power generation system, the brazed power generation system component, and braze are provided to improve repairing power generation systems. The method includes providing the component having a feature in a surface of the component and coating a particulate material with a filler material to obtain a coated particulate material. The method includes preparing the feature to obtain a treatment area and filling the treatment area in the surface of the component with the coated particulate material. The method includes heating the treatment area and surrounding component to a brazing temperature and applying oxidation protection to the treatment area. After the brazing temperature is obtained, the method includes brazing the treatment area and the screen and cooling the component to obtain a brazed joint.
摘要:
An electric discharge machining process, an article for electric discharge machining, and an electrically-conductive electric discharge machining coolant are disclosed. The electric discharge machining process includes electric discharge machining a target region of a component. The article includes a non-electrically-conductive layer, an electrically-conductive layer, and a target region on the non-electrically-conductive layer. The electrically-conductive electric discharge machining coolant includes a hydrocarbon liquid and carbon powder suspended within the hydrocarbon liquid.
