Abstract

A turbocharger impeller 1, for connection to a shaft 2, is formed from a metal matrix composite material having an aluminium alloy matrix and silicon carbide particulate reinforcement. The average particle diameter of the particulate reinforcement may be 2 microns or less. The particulate reinforcement may be from 10% to 30% of the composite by volume. The impeller may be fitted with a connector 3. The connector may frictionally engage an inner or outer surface of a shaft-side hub extension H of the impeller. The connector may have a threaded portion 12 which screws onto a corresponding threaded portion 7 of the shaft. The material of the connector may have a coefficient of thermal expansion which is equal to or greater than that of the composite material of the impeller. The material of the connector may have a greater strength than the composite material of the impeller.
