초록

The invention relates to a guide vane (17) for a turbomachine (1), in particular a gas turbine guide vane, in which the platform (48) has a separating region (50), which is embodied as a separate component. This has, in particular, advantages with respect to the simplification of cast blade/vane (17) in terms of manufacturing technology, with respect to the variability of a material selection, the quality of a protective coating to be applied and efficient cooling.
