A remanufactured planet carrier is disclosed having a first plate and a second plate spaced apart from and oriented generally parallel to the first plate. Supports join and support the first and second plates. The remanufactured planet carrier further has a plurality of first pin bores in the first plate and a plurality of second pin bores in the second plate. The first pin bores are parallel and generally aligned with the second pin bores. A cylindrical member extends from a central axis of the second plate away from the first plate with a shaft bore formed within the cylindrical member. The first and second pin bores and the shaft bore each have a surface layer with a hardness of at least about 180 BHN and a strength of at least about 500 MPa.

A power rail includes an aluminum body and a wear coating including stainless steel. The power rail may also include a break-in coating having a lower hardness than the wear coating.

Coated power rail

A method of coating a component is disclosed. The method includes applying a coating composition to a surface of the component. The method also includes providing an induction coil having a coil configuration corresponding to the surface. The method further includes relatively positioning the surface and the induction coil with a gap sufficient to enable induction heating of the surface by the induction coil. Furthermore, the method includes heating the component with the induction coil sufficient to produce a coating having an empirical formula FeMnO, where x varies from about 0 to about 2, y varies from about 1 to about 4, and z varies from about 2 to about 8.
