A fan blade assembly with wear mitigation characteristics is disclosed. In a titanium hub, dovetail shaped slots are used for accommodating dovetail shaped roots of fan blades. At least the inwardly facing walls of the dovetail shaped slots are coated with a dry film lubricant. The inwardly directed pressure faces of the dovetail shaped root of the fan blades are covered with polymeric wear mitigation pads. The combination of wear mitigation pads on the pressure faces of the root of the fan blade in combination with a dry film lubricant coating on the inwardly directed walls of the dovetail shaped slots in the hub provide excellent wear mitigation characteristics and prolong the life of the fan blades.
