The curved shape can be defined by one or more radii of curvature (RC, RC1, RC2). The diffuser (450, 550, 650, 750, 850, 950) can extend in a radial direction that is non-orthogonal to the center line of the turbocharger (400, 500, 600). The housing (410, 510, 610, 700, 800, 900) can be for a compressor section of the turbocharger (400, 500, 600).

摘要： A rotor shaft assembly (101) of a type used in a turbocharger, manufactured by mounting a powder compact of a titanium aluminide rotor (203) to a powder compact of a steel shaft (207), with a metal powder admixed with a binder (211) interposed between the rotor and shaft, and debinding and sintering the mounted compact combination. Sintering produces a strong metallurgical bond between the shaft and rotor, providing a near-net rotor shaft assembly (101) and also an inexpensive and efficient method for the manufacture of an assembly capable of withstanding the high forces and temperatures within a turbocharger.
