A rotor shaft assembly for use in turbochargers includes a metal shaft having a generally cylindrical female cavity therein concentrically distributed about the axis thereof; and a solid hubbed ceramic turbine wheel having a male stub shaft insertable into the female cavity. The axis of the male stub shafted ceramic turbine is coextensive with the axis of the shaft and the stub shaft is mated with the female receptacle and joined by an adhesive. A turbocharger includes a rotor-shaft assembly of the above-described type, in which the metal to ceramic adhesive joint is located in the turbocharger center housing.
