    摘要： A mold assembly (301) for use in forming a component having an internal passage defined therein is provided. The component is formed from a component material. The mold assembly includes a mold (300) that defines a mold cavity (304) therein. The mold assembly also includes a lattice structure (340) selectively positioned at least partially within the mold cavity. The lattice structure is formed from a first material (322) that is at least partially absorbable by the component material in a molten state. A channel (344) is defined through the lattice structure, and a core (324) is positioned in the channel such that at least a portion (315) of the core extends within the mold cavity and defines the internal passage when the component is formed in the mold assembly.

    摘要： Casting molds (10, 56) suitable for directional solidification processes using a liquid cooling bath (60) include a graded facecoat structure (12) on a mold body (20). The graded facecoat structure (12) includes an innermost layer (14) and a delamination layer (18), wherein the delamination layer (18) fractures upon cooling of the molten metal so as to separate the mold body (20) from the innermost layer (14), which remains in contact with or in close proximity to the metal being cast. Also disclosed are directional solidification processes.

    摘要： Shell molds and processes for making the shell molds that exhibit high emissivity in the red and infrared regions are described. In this manner, thermal resistance within a gap formed between solidifying cast metal and the interior mold surface is decreased. In one embodiment, the facecoat region is formed from a slurry composition comprising an aluminum oxide, a green chromium oxide and a silicon dioxide. In another embodiment, the facecoat region is formed from a slurry composition including zirconium silicate and silica with stucco layer of alumina is included.

    摘要： A process for chemically stripping a metallic coating on an external surface of a substrate (10) without attacking an internal surface defined by an internal passage (18) within the substrate (10). Processing steps include depositing within the internal passage (18) a thermally-decomposable wax (20) having a melting temperature above 75°C so as to mask the internal surface of the substrate (10), and then treating the substrate (10) with an aqueous solution containing an acid having the formula H x AF 6 where A is silicon, germanium, titanium, zirconium, aluminum, or gallium, and x has a value of one to six. The aqueous solution is at a temperature below the melting temperature of the wax (20) and substantially removes the metallic coating from the external surface of the substrate (10), while the wax (20) is substantially unreactive with the aqueous solution and prevents the aqueous solution from contacting the internal surface of the substrate (10). Thereafter, the substrate (10) is heated to thermally decompose the wax (20) without producing hazardous byproducts.
