1. A fan slider for mounting on a gas turbine engine, the fan slider comprising: a body including a plurality of bores defined therein and extending through the body between an upper surface and a lower surface; anda coating disposed within the plurality of bores, forming reinforcement pins, and on an exterior surface of the body, the exterior surface including the upper surface and the lower surface, the coating comprising nanocrystalline metallic material. 2. The fan slider of claim 1, wherein the body has an exterior surface that includes an upper surface formed to include a central groove defined therein. 3. The fan slider of claim 2, wherein the coating covers substantially all of the body. 4. The fan slider of claim 2, further comprising a metallic return spring arranged within the central groove to urge a fan blade towards an outer diameter of a fan wheel when the fan slider is assembled into a fan assembly. 5. The fan slider of claim 4, wherein the metallic return spring is coupled to the coating by one of an adhesive, a weld, or a fastener. 6. The fan slider of claim 1, wherein the coating has a thickness from about 0.001-0.150 inches at all points along the exterior surface of the fan slider body. 7. The fan slider of claim 1, wherein the body is formed of a polymer selected from the group consisting of polyether ether ketone, acrylonitrile butadiene styrene, polyethylenimine, and Nylon GF. 8. The fan slider of claim 1, wherein the coating comprises nickel-based alloy coating. 9. A method of making a fan slider for use in a fan assembly to push a fan blade radially outward of a rotating axis of a gas turbine engine, the method comprising the steps of: forming a body of a polymer;forming bores penetrating through the body; andcoating an exterior surface of the body with a nanocrystalline metallic coatingincluding filling the bores with the nanocrystalline metallic coating and forming reinforcement pins that extend through the body. 10. The method of claim 9, wherein forming the fan slider body is selected from the group consisting of injection molding and extruding. 11. The method of claim 9, wherein the polymer is selected from the group consisting of polyether ether ketone, acrylonitrile butadiene styrene, polyethylenimine, and Nylon GF. 12. The method of claim 9, wherein the nanocrystalline coating is nickel-based alloy coating. 13. The method of claim 9, further comprising, after the step of coating the body, removing the polymer from the nanocrystalline metallic coating. 14. A method of making a fan slider for use in a fan assembly to push a fan blade radially outward of a rotating axis of a gas turbine engine, the method comprising the steps of: forming a fan slider body of a polymer;forming holes through the fan slider body;coating the fan slider body with a nanocrystalline metallic coating including filling the holes formed through the fan slider body with the nanocrystalline metallic coating; andremoving the fan slider body from the fan slider by heating the polymer that makes up the fan slider body and leaving a shell of the nanocrystalline coating. 15. The method of making a fan slider of claim 14, further comprising mounting a slider spring to the shell. 16. The method of making a fan slider of claim 14, wherein filling the holes with the nanocrystalline coating forms reinforcement pins that extend through the body.
