Notizen:
Dynamic fatigue behavior of two kinds of Y-TZP ceramics was investigated at roomtemperature. The results showed that dynamic fatigue and slow crack growth behaviors exist in zirconias.Crack growth exponents of original and pre-cracked samples were obtained. Crack growth exponents ofthe two original zirconias are 15.60 and 21.00, respectively. Crack growth exponents of annealedpre-cracked samples are close to the original samples, indicating that the pre-crack experimental methodis reasonable and effective. Because of the influence of residual stress indcued by indentation, crackgrowth exponents of unannealed samples are different from that of original samples. So residual stressshould be removed
