Abstract
A flow body for a gas turbine includes an airfoil extending along a radial direction between a platform end and a tip which has a tip surface. The airfoil is formed of a first metal material and comprises an inner cavity for receiving a gaseous cooling fluid. The flow body further includes a squealer tip protruding from the tip surface of the tip and extending along a circumference of the tip so that the squealer tip at least partially surrounds the tip surface. The squealer tip is formed from a second metal material and includes a plurality of internal cooling cavities that are separated from each other within the squealer tip, wherein each of the internal cooling cavities is in fluid communication with the inner cavity via one or more fluid passages.
