摘要：A rotor blade, a rotor disc (24) or load bearing assembly having at least onebearing surface (22) for contact with a corresponding bearing surface (28). At least one
selected area of the bearing surface (30,32) which, in operation, is an area of alternatingstress greater than about 50 MPa (peak to peak), is configured to have a co-efficient offriction lower than the remainder of the bearing surface (34). The selected area (30,32)having a co-efficient of friction lower than the remainder of the bearing surface (34) maybe provided by the application of a dry film lubricant, with the remaining area(s) (34) ofsaid bearing surfaces (22) being substantially free of the said coating.
