Abstract
A rotor shaft assembly () of a type used in a turbocharger, manufactured by mounting a powder compact of a titanium aluminide rotor () to a powder compact of a steel shaft (), with a metal powder admixed with a binder () 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 () and also an inexpensive and efficient method for the manufacture of an assembly capable of withstanding the high forces and temperatures within a turbocharger.
