Method of strengthening ceramic bodies and strengthened ceramic bodies produced thereby
Abstract
Abstract A METHOD OF INCREASING THE BENDING STRENGTH AND THERMAL SHOCK CHARACTERISTICS OF SINGLE CRYSTAL AND POLYCRYSTALLINE CERAMIC BODIES AND STRENGTHENED CERAMIC BODIES PRODUCED THEREBY. THE BODIES ARE STRENGTHENED BY FORMING AT LEAST ON ONE SURFACE THEREOF AT AN ELEVEATED TEMPERATURE A LAYER OF LOW EXPANSION MATERIAL WHICH IS A MATERIAL COMPOSEED AT LEAST PARTLY OF THE MATERIAL WHICH IS THE BODY AND WHICH AT THE LEAST HAS A COEFFICIENT OF EXPANSION WHICH IS LESS THAN THAT OF THE MATERIAL OF THE BODY. THE MATERIAL CAN ALSO HAVE AN INCREASED VOLUME, AND CAN BE A SOLID SOLUTION OR THE MATERIAL OF THE BODY IN A CHANGED PHASE. THE BODY IS THEN COOLED SO AS TO PRODUCE ON THE SURFACE OF THE BODY A LAYER WHICH IS UNDER COMPRESSION RELATIVE TO THE BODY.
