摘要： A rotor (121) for a turbomachine and a method of manufacturing the same. The method includes providing a lug (232) with a lug body (266) and an interface material (268) disposed on the lug body. The method also includes friction welding (235) the lug to a hub member (230) via the interface material to define a projected structure (212) for an outer radial area of a disc assembly (124) of the rotor. The projected structure is configured to support a first side (125) of a rotor blade (126) of the rotor in cooperation with a second projected structure of the disc assembly supporting a second side (127) of the rotor blade. The lug body and the hub member are made from different materials.
