ABSTRACT:
A strengthened article formed from a ceramic having a bore through a portion thereof and with a metal rod adhered by heat-settable adhesive to the ceramic within the bore thereof. The metal rod has a greater coefficient of thermal expansion than the ceramic thereby placing this ceramic in compression upon heat setting and cooling of the overall article.
