Abstract

A rotating assembly (31) for a turbomachine (2) includes a plurality of rotating members (46) that extend radially outward from a central hub (47). Each of the plurality of rotating members (46) includes a base portion (48) detachably mounted to the central hub (47), a tip portion (49), a mid-span portion (50) that extends between the base portion (48) and the tip portion (49), and a shroud portion (60, 70) positioned at one of the tip portion (49) and the mid-span portion (50). The shroud portion (60, 70) includes a pressure side (73) and a suction side (72). At least one hard face interface member (100, 120) is secured to at least one of the suction side (72) and the pressure side (73) of the shroud portion (60, 70). The at least one hard face interface member (100, 120) is both mechanically interlocked with, and metallurgically bonded to, the shroud portion (60, 70).
