    摘要： A rotating structure (20) of a gas turbine engine is provided by furnishing a rotor disk (22) comprising a hub (24) with a plurality of hub slots (26) in a periphery of the hub (24), each hub slot (26) having a hub slot surface (32), and furnishing a plurality of rotor blades (34). A protective coating (80) is deposited by a wire spray process at a location which will be, upon assembly, disposed between a root (38) of each rotor blade (34) and the respective hub slot surface (32). The protective coating (80) is a protective alloy having, in weight percent, from about 6.0 to about 8.5 percent aluminum, from 0 to about 0.5 percent manganese, from 0 to about 0.2 percent zinc, from 0 to about 0.1 percent silicon, from 0 to about 0.1 percent iron, from 0 to about 0.02 percent lead, remainder copper and impurities. The rotor blades (34) are assembled into the hub slots (26) of the rotor disk (22) to form the rotating structure (20), which is then operated at a temperature such that the root (38) is at a temperature of from about 75°F to about 350°F.
