Abstract: A compressor wheel that can be employed in devices such as turbochargers. The compressor wheel includes an axially extending hub having an inlet end, a shaft bore extending from the inlet end and an arcuate outer surface opposed to the shaft bore. The axially extending hub is composed of a metal and has a porous region located proximate to the arcuate outer surface of the axially extending hub. The compressor wheel also includes a blade array disposed on the arcuate outer surface of the axially extending hub. The blade array has an outer surface and an inner region. The blade array comprises a plurality of circumferentially-spaced, radially and axially extending blades disposed thereon and is composed, at least in part of a polymeric material. Polymeric material located in the inner region of the blade array extends into the porous region defined in the axially extending hub.
