Turbine bucket with metallic airfoil and ceramic tip cap, and corresponding gas turbine engine

摘要

A turbine bucket (24) may generally include an airfoil (30) formed from a metal-based material. The airfoil (30) may include a base (34) and a tip (36) disposed opposite the base (34). The airfoil (30) may also include a pressure side wall (38) and a suction side wall (40) extending between a leading edge (42) and a trailing edge (44). Additionally, the turbine bucket (24) may include a tip cap (26) disposed between the pressure side wall (38) and the suction side wall (40). The tip cap (26) may be formed from a ceramic matrix composite material. A corresponding gas turbine engine is also provided.
