Bonding of TRIP-Steel/Al2O3-(3Y)-TZP Composites and (3Y)-TZP Ceramic by a Spark Plasma Sintering (SPS) Apparatus
A combination of the high damage tolerance of TRIP-steel and the extremely low thermal conductivity of partially stabilized zirconia (PSZ) can provide controlled thermal-mechanical properties to sandwich-shaped composite specimens comprising these materials. Sintering the (TRIP-steel-PSZ)/PSZ sandwich in a single step is very difficult due to differences in the sintering temperature and densifi...
متن کاملPreparation and Optical Properties of Infrared Transparent 3Y-TZP Ceramics
In the present study, a tough tetragonal zirconia polycrystalline (Y-TZP) material was developed for use in high-speed infrared windows and domes. The influence of the preparation procedure and the microstructure on the material's optical properties was evaluated by SEM and FT-IR spectroscopy. It was revealed that a high transmittance up to 77% in the three- to five-micrometer IR region could b...
متن کاملThe Effects of Spark-Plasma Sintering (SPS) on the Microstructure and Mechanical Properties of BaTiO3/3Y-TZP Composites
Composite ceramics BaTiO₃/3Y-TZP containing 0 mol %, 3 mol %, 5 mol %, 7 mol %, and 10 mol % BaTiO₃ have been prepared by conventional sintering and spark-plasma sintering (SPS), respectively. Analysis of the XRD patterns and Raman spectra reveal that the phase composition of t-ZrO₂, m-ZrO₂, and BaTiO₃ has been obtained. Our results indicate that SPS can be effective for the decrease in grain s...
متن کاملSurface Bioactivity of Sol Gel Derived 3Y-TZP Bioinert Ceramic through Hydroxylation Technique Using 5M H3PO4
Problem statement: This study presented bone like apatite formation on yttria stabilized zirconia in Simulated Body Fluid (SBF) through hydroxylation technique. Approach: Sol gel route was used to prepare yttria stabilized zirconia. Then it was hydroxylated with 5M H3PO4 for formation of Zr-OH group. Moreover, the growth rate of calcium and phosphate on zirconia substrate was examined using sim...
متن کاملCeramic Composites of 3Y-TZP Doped With CuO: Processing, microstructure and tribology
In recent years, 3 mol% yttria stabilized tetragonal zirconia polycrystals (3Y-TZP) doped with copper oxide has obtained increasing interest due to its enhanced superplasticity and good potential in tribological applications. In this work, the effect of addition of small amounts (0.8 mol%) of CuO on the sintering behaviour of 3Y-TZP was studied using a dilatometer and high temperature X-ray dif...
