The aim of the study is to carry out a comparative analysis of the phase composition of conventional zirconium with the predominance of tetragonal phase after artificial aging and loading. The studied group included samples of conventional zirconia stabilized with 3 mol% yttrium (3YTZP). The X-ray diffraction analysis of these samples was carried out on an automatic X-ray diffractometer for polycrystalline materials DRON-7 in the step-by-step scanning mode. The following studies included flexural strength before and after aging, cyclic loading before and after aging, cyclic load after aging 100-200 N, 500 - 800 N, phase analysis in the area of the crack and without crack. The diffraction patterns correlate well with each other and indicate basically the same crystal structure of the ZrO2 compound. All X-ray diffraction patterns show only the ZrO2 phase with a tetragonal crystal lattice. It was not found that the aging, cracks and loads performed affects the phase composition and microstructure of the samples under study. The presence of cracks and loads in this case does not affect the phase composition and microstructure of the material. Samples are almost identical. It should be noted that this method is integral (volumetric) and does not allow localizing studies only in the area of the cracks and loads. [ABSTRACT FROM AUTHOR] |
