PROCESSES FOR PRODUCING COMPONENTS CONTAINING CERAMIC-BASED AND METALLIC MATERIALS

摘要

Processes for producing a component (30,80,100) containing a ceramic-based material and having detailed features formed from materials other than ceramic materials. Such a process entails producing the component (30,80,100) to include a first subcomponent (44,82,102) and at least a second subcomponent (46,90,104) having at least one off-axis geometric feature (34,36,42,92,96,104) that results in the second subcomponent (46,90,104) having a more complex geometry than the first subcomponent (44,82,102). The first subcomponent (44,82,102) is formed of a ceramic-based material, and the second subcomponent (46,90,104) and its off-axis geometric feature (34,36,42,92,96,104) are separately formed of a metallic material and attached to the first subcomponent (44,82,102) to yield a robust mechanical attachment. The component (30,80,100) may be, for example, a gas turbine airfoil component (30,80,100).
