    摘要: PROBLEM TO BE SOLVED: To provide a method related to the formation of a recessed part in a component for constituting a high temperature gas passage for a turbine assembly. SOLUTION: The method comprises forming at least one recessed part having a selected size and shape in the surface of an inner passage of the metal component. The method includes a step of stacking a ceramic base material (50) on a ceramic core suitable to forming the inner passage by a direct writing method during a casting process for forming the metal component and stacking the ceramic base material as a positive characteristic part, a step of heat treating the stacked ceramic base material, a step of forming the metal component by the casting method by which the ceramic core (56) is incorporated in a cast product at a position selected as a desired position for the inner passage, and a step of removing the ceramic core from the metal component after completion of the casting process, and forming the inner passage having the recessed part in the surface of the passage by removing the positive characteristic part of the ceramic base material.
