Abstract

The aim of this study was to prepare and to characterize the structure of Al₂O₃-3YSZ composites with 5% TiO₂ addition as well as the surface modification upon treatments with SnF₂ and NaBF₄, respectively. SEM micrographs showed the controlled densification of the composites as an effect of 3YSZ and TiO₂ addition to alumina matrix. By FTIR and XRD, the characteristics of Al-O and Zr-O vibrations, respectively, the diffractions lines related to α-corundum and zirconia in tetragonal phase were discussed. Qualitative and quantitative results obtained by XPS and ATR FTIR demonstrated that the proposed materials are more sensitive to SnF₂ than to NaBF ₄ treatment.
