Abstract: Components for an automatic motor vehicle transmission including a band brake drum, a clutch housing or hub having a seal surface or a clutch housing or hub utilized in a friction clutch assembly having a spline set. All of these components are fabricated of aluminum and the outer surface of the band brake drum, the housing or hub sealing surface and the area of the spline set includes a thin coating of a thermally sprayed steel material. The thermally sprayed steel material may be a low carbon steel such as SAE 1008 or 1010, a similar alloy, iron or other metal. The resulting components thus exhibit the weight saving of aluminum while providing excellent service life due to the enhanced strength and wear resistance provided by the thermally sprayed steel coating.
