Abstract

The results of studies of the structural and mechanical properties of aluminum-zirconium composite ceramics with different ratios of Al₂O₃ (white electrofused corundum F-1000) and 3Y-TZP (tetragonal polycrystalline ZrO₂ stabilized with 3,0 mol. % Y₂O₃) obtained by semidry molding followed by free sintering are presented. According to microstructural studies, the introduction of a eutectic additive in the composition of ceramics leads to the formation of a specific structure of the material of the type «composite in composite». It was shown that an increase in the content of the eutectic additive in the alumina matrix increases the relative density of the composite from 93.5 to 98,8 %. Changes in the composition and microstructure of ceramics affect its mechanical properties.
