ZTA tubes were prepared by centrifugal casting and sintered at for 2 hrs. The ZTA tubes were machined into specimens of mm. Molten Soda lime glass (SLG) was penetrated into the surface of ZTA at an optimized condition of for the holding time of 5 h and furnace cooled. The extra glass on the surface was removed using a resin bonded diamond wheel. The glass penetrated samples were tested for their flexural strength using four point bend test. Vickers Indentation cracks were made on the glass penetrated surface at different loads of 9.8 N, 49 N, 98 N and 196 N. The residual compression on the surface enhanced the flexural strength and crack arrest behaviour remarkably. This was attributed to the thermoelastic mismatch between the glass and ZTA matrix during cooling.

Keywords:residual compression;glass penetration;thermo-elastic mismatch;soda lime glass;ZTA
