ABSTRACT:
A composite assembly includes a ceramic inner member and an outer shell member fit around the inner member. The outer shell member is heated and expanded, the two members then are mutually located at predetermined positions relative to each other, and the members are cooled such that the outer shell member shrinks onto the inner member. Heating of the outer shell member is achieved by an inductive heater to result in the predetermined temperature, after which the inner member is moved to the predetermined position thereof relative to the outer shell member, while the outer shell member is maintained at such predetermined temperature.
