Zusammenfassung:A bucket assembly (30) is disclosed. The bucket assembly includes an airfoil (32) having a generally aerodynamic contour and defining a tip (52), and a lower body portion (34) extending generally radially inward from the airfoil (32). The bucket assembly further includes a tip shroud (60) disposed on the tip (52) of the airfoil (32) and comprising a main body (62) and a rail (64). The rail (64) includes an exterior surface (66). The exterior surface (66) defines one or more microchannels (80). The bucket assembly (30) further includes a cover layer (82) configured on the exterior surface (66). A corresponding turbine system (10) is also provided.
