Abstract: A number of variations may include a vehicle which may have a vehicle body and a vehicle hub operably coupled to the vehicle body. A vehicle wheel may be operably coupled to the vehicle hub. The vehicle wheel may be isolated from the vehicle hub by at least one isolation feature selected from the group consisting of: an extended flange portion of the vehicle wheel may be disposed between a pilot hole and the vehicle hub, a multiple piece cover portion may fully cover the pilot hole, a drain slot may be disposed on the vehicle wheel and the drain slot may have a slope of at least five degrees, or an enhanced bushing may create a non-flat profile between the vehicle wheel and a fixation device.

Abstract: A metal workpiece, such as a wheel, and a method of providing an enhanced corrosion resistant surface coating on an exposed surface of a metal or alloy substrate (such as magnesium). A corrosion resistance basecoat is formed, including generating an oxide layer, and applying a first primer coating onto at least a portion of the oxide layer. The method may further include identifying highest corrosion prone areas on the substrate and designing a support rack that avoids contact with these corrosion prone areas. The method also includes forming a topcoat over at least a portion of the basecoat, by applying a second primer coating onto at least a portion of the first primer coating and depositing a sputtered metallic film onto the second primer coating using a physical vapor deposition technique. A clear coat layer may be applied over the metallic film.
