英文摘要

Different particle size 3mol% Y2O3-stabilized tetragonal zirconia polycrystalline (3Y-TZP) coated with CePO4 was prepared by a coprecipitationmethod and the effect of zirconia particle-size on its mechanical properties was investigated. Thephase composition and microstructure of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), respectively. The machining characteristic of as-prepared samples was calculated to be 0.54 for a zirconia particle size of around 30-50 nm. In this grain size range, the hardness, fracture toughness, and bending strength of the coated sample were found to be 10.72GPa, 5.76MPa.m(1/2), and 463MPa. Our results show that the grain size of the zirconia before coating greatly influences the mechanical properties of the coated samples because the different particle sizes result in different fracture styles.
