    摘要： Method and assembly for joining a first component and a second component. The method comprises positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component, inserting a solid retainer material into the joint region through an aperture in one of the first component or the second component to form a mechanical interlock between the first component and the second component, and sealing the aperture to retain the solid retainer material within the joint region. The solid retainer material includes at least one of a metal, a metal alloy, or a ceramic. The solid retainer material does not melt while forming the mechanical interlock. An assembly is also disclosed.

    摘要： A method includes removing a casting shell and core from a cast component, which may be a gas turbine blade. The method further includes utilizing a focused removal technique, such as a water jet or laser drill, to remove a portion of a virtual pattern cast (VPC) shell from the cast component. The cast component is then exposed to a leaching solution and high pressure water wash to remove an internal core material and a portion of the VPC shell remainder from the cast component. The method further includes exposing the cast component to a high agitation leaching solution and to the high pressure water wash for a minimal time. An electroless nickel-boron coating is then applied to the cast component, and an electrolytic palladium coating is further applied to the cast component. The cast component is further exposed to a high agitation leaching solution for an extended period.

    摘要： A green ceramic casting mold system comprises a shell having a thin outer wall member with a substantially smooth as formed inner surface defining a complex shaped volume adapted for receiving a molten metallic material. The thin outer wall member is a layered structure of ceramic particles bound together by a polymer binder. A core is positioned within the volume and adapted to create at least one passage within the component formed from the molten metallic material received in the volume. The core is a layered structure of ceramic particles bound together by an organic polymer binder.
