Lifetime Control and Prediction of ZrO2/CePO4 Composites
Based on the relation between the stress intensity factor Ki and the crack velocity V, lifetime prediction and control were discussed and studied for machinable Ce-ZrO2/CePO4 ceramics. The relationship among lifetime, starting cracks and grain sizes were investigated by a set of designed simulation setting with a definite actual environmental conditions. It was concluded that crack started from larger weak interfaces of two phases and linking of cracking weak interfaces each other, and the lifetime of Ce-ZrO2/CePO4 composites could be controlled and predicted by adjusting of grain sizes of CePO4, which was depended on design of composites.
