A mold assembly for use in forming a component having an internal passage defined therein includes a mold defining a mold cavity therein, and a jacketed core positioned with respect to the mold. The jacketed core includes a hollow structure, and an inner core disposed within the hollow structure and positioned to define the internal passage within the component when a component material in a molten state is introduced into the mold cavity and cooled to form the component. The jacketed core also includes a first coating layer disposed between the hollow structure and the inner core.

1. A method of forming a component having an internal passage defined therein, said method comprising: applying at least a first coating layer to an interior portion of a preformed hollow structure, wherein the hollow structure is formed from a first material that is metallic;after said applying the at least first coating layer, disposing an inner core within the hollow structure to form a jacketed core;positioning the jacketed core with respect to a mold;introducing a component material in a molten state into a cavity of the mold, such that a portion of the jacketed core is submerged, and such that the component material in the molten state contacts the first material along substantially an entire outer perimeter of the submerged portion of the jacketed core; andcooling the component material in the cavity to form the component, wherein the inner core is positioned to define the internal passage within the component, and at least a portion of the first coating material lines at least a portion of the internal passage. 2. The method of claim 1, wherein positioning the jacketed core comprises positioning the jacketed core wherein the at least first coating layer includes a first coating material selected from one of (i) an oxidation-inhibiting material, (ii) a corrosion-inhibiting material, (iii) a carbon-deposition-inhibiting material, (iv) a thermal barrier material, (v) a water vapor barrier material, and (vi) a wear-inhibiting material. 3. The method of claim 1, wherein positioning the jacketed core comprises positioning the jacketed core wherein the at least first coating layer includes a plurality of coating layers disposed between the hollow structure and the inner core. 4. The method of claim 3, wherein positioning the jacketed core further comprises positioning the jacketed core wherein the at least first coating layer includes a first coating material selected from one of (i) an oxidation-inhibiting material, (ii) a corrosion-inhibiting material, (iii) a carbon-deposition-inhibiting material, (iv) a thermal barrier material, (v) a water vapor barrier material, and (vi) a wear-inhibiting material, and a second of the plurality of coating layers is formed from a second coating material selected from another of (i) an oxidation inhibiting material, (ii) a corrosion-inhibiting material, (iii) a carbon-deposition-inhibiting material, (iv) a thermal barrier material, (v) a water vapor barrier material, and (vi) a wear-inhibiting material. 5. The method of claim 3, wherein positioning the jacketed core further comprises positioning the jacketed core that includes a second of the plurality of coating layers formed from a bond coat material. 6. The method of claim 1, wherein applying the at least first coating layer comprises applying the at least first coating layer to the interior portion of the hollow structure in a bulk coating process. 7. The method of claim 6, wherein applying the at least first coating layer comprises applying the at least first coating layer to the hollow structure in at least one of a vapor phase deposition process and a chemical vapor deposition process. 8. The method of claim 1, wherein applying the at least first coating layer comprises applying the at least first coating layer to the interior portion of the hollow structure in at least one of a slurry injection process and a slurry dipping process. 9. The method of claim 1, wherein the hollow structure is formed incrementally, and applying the at least first coating layer comprises applying the at least first coating layer to a plurality of incremental portions of the hollow structure. 10. The method of claim 1, wherein applying the at least first coating layer comprises applying the at least first coating layer in an additive manufacturing process. 11. The method of claim 1, wherein disposing the inner core comprises injecting an inner core material as a slurry into the hollow structure.
