Al2O3/SiC composite ceramics with high crack-healing ability were subjected to shot peening (SP) using zirconium oxide shots with several peening pressures and shot diameters. Specimens subjected to SP were heat-treated in air to heal the surface cracks induced by SP. The residual stress, the apparent fracture toughness, and the Weibull distribution of the contact strength were investigated, revealing that the combination of SP and crack-healing is effective for increasing the contact strength and decreasing the scatter of the contact strength of Al2O3/SiC.

In this study the combination effects of shot peening (SP) and crack-healing on the contact strength of ceramics were examined. Si3N4/SiC composite ceramics with high crack-healing ability were used and the specimens were subjected to shot peening with several peening pressures and shot diameters. Then, some specimens subjected to SP were heat-treated in air to heal surface cracks introduced by shot peening. Sphere indentation tests were carried out on the specimens and investigated the Weibull distribution of the contact strength. As a result, it is found that the combination of shot peening and crack-healing is effective to increase contact strength and decrease the scatter of the contact strength.
