    摘要: A method of forming a ceramic layer on a metal substrate. A substrate (40) is formed (54) from a powder (24) of the metal, and may optionally be partially sintered (56). A layer (43) of powdered ceramic is formed (58) on or applied against the substrate (45). The ceramic powder may include a proportion of nano-sized particles effective to reduce the ceramic sintering temperature and to increase the sintering shrinkage of the ceramic layer to more closely match that of the metal substrate. The substrate and layer are then co-sintered (21, 60) at a temperature and for a duration that densifies and bonds them, producing a metal/ceramic layered material system with low interface stress that is durable to temperature variations in a gas turbine. Spark plasma sintering (32, 34, 36) may be used to sinter and/or co-sinter substrate and layer materials that normally cannot be sintered.

    摘要: A turbine airfoil usable in a turbine engine and including a depth indicator for determining outer wall blade thickness. The airfoil may include an outer wall having a plurality of grooves in the outer surface of the outer wall. The grooves may have a depth that represents a desired outer surface and wall thickness of the outer wall. The material forming an outer surface of the outer wall may be removed to be flush with an innermost point in each groove, thereby reducing the wall thickness and increasing efficiency. The plurality of grooves may be positioned in a radially outer region of the airfoil proximate to the tip.

    摘要: A method of manufacturing a component, including providing a three-dimensional computer model of the component to be produced; deconstructing the three-dimensional computer model by defining a plurality of model slices; forming a plurality of metallic foils, where each foil corresponds to a specific model slice; assembling the plurality of formed foils in a tool to form a three-dimensional component stack; and bonding the three-dimensional component stack to form the component. Characteristics of the foils may differ in various portions of the stack, such as being a different material, having a different thickness, or having a different grain orientation. The control of dimensional tolerances of internal structures, such as cooling passages, in three dimensions is devolved into two separate steps of 1) selecting a thickness of each slice/foil, and 2) controlling in two dimensions a material removal process applied to the respective foil.
