Abstract

Cracking in ceramics poses a serious threat to the safety of components. In the study of crack healing, SiO2 was the healing material. In this study, TiO2 was added to improve the strength of ceramics, and SiO2 was added or coated to heal cracking. These show effectiveness by heat treatment. The bending strength increased by adding TiO2 and SiO2, and the friction coefficient and wear loss were smaller than that of the non-addition
