Abstract
A wheel includes a hub portion configured to rotate about a rotational axis. A plurality of blades extends radially outward from the hub portion. Each blade of the plurality of blades includes a leading edge and a trailing edge. The hub portion and the plurality of blades include a substrate metal. The substrate metal of the plurality of blades has coated directly thereon a coating layer that has a hardness of about 800 HV or greater and that includes electroless nickel-phosphorous having a phosphorous content of from about 2 to about 4 wt. %.
