Abstract
The connection of a ceramic rotary component to a metallic rotary component for a turbomachine such as a gas turbine engine wherein the ceramic rotary component comprises a sintered rotor disk of reaction bonded silicon nitride (RBSN) or silicon carbide sintered under no pressure and the metallic rotary component is formed by the hot isostatic pressing of a metallic powder. The metallic rotary component becomes bonded to the sintered rotor disk to form a secure connection therewith. The metallic powder has a coefficient of thermal expansion substantially equal to that of the ceramic rotary component.
