Abstract
A compressor wheel (10) that can be employed in devices such as turbochargers. The compressor wheel (10) includes an axially extending hub (12) having an inlet end (18), a shaft bore (22) extending from the inlet end (18) and an arcuate outer surface (20) opposed to the shaft bore (22). The axially extending hub (12) is composed of a metal and has a porous region (34) located proximate to the arcuate outer surface (20) of the axially extending hub (12). The compressor wheel (10) also includes a blade array (24) disposed on the arcuate outer surface (20) of the axially extending hub (12). The blade array (24) has an outer surface (27) and an inner region (29). The blade array (24) comprises a plurality of circumferentially-spaced, radially and axially extending blades (26) disposed thereon and is composed, at least in part of a polymeric material. Polymeric material located in the inner region (29) of the blade array (24) extends into the porous region (34) defined in the axially extending hub (12).
