Contribution to the Understanding of the Dielectric Breakdown Mechanism of Zta Ceramics

SSRN Electronic Journal, 2022
Herein, the breakdown mechanism of alumina‐based ceramics (Al2O3–ZrO2) is studied. The specimens are characterized for their density, phase structure, micromorphology, breakdown process, and breakdown channel by micro computed tomography, high‐speed cameras, etc.

COMPETITIVE LIFE TIME ASSESSMENT OF SrO-ZTA/SrO-ZTA AND CoCrMo/UHMWPE HIP PROSTHESIS BEARINGS

Journal of Mechanics in Medicine and Biology, 2020
The hip joint envisages the prime load bearing structure among other joints in the human body. Hip joint failure leads to the replacement of the hip joint prosthesis. This research work focuses on the proper selection of bearing couple materials for the hip joint to improve the performance and life.

The thermal conductivity of ZTA graphite

Carbon, 1967
Abstract Measurements of the thermal conductivity of ZTA graphite from −100°C to 2700°C are reported. Three different methods were used to cover the temperature range: a transient technique, a series comparison method, and a radial heat flow method.

Corrosion Behaviour of ATZ and ZTA Ceramic

Key Engineering Materials, 2007
The aim of this study was to record corrosion behaviour of ZTA and ATZ ceramics under hydrothermal conditions and under influence of boiling acids. Ageing was performed for 30 h and for 100 h in an autoclave at 134 °C and at a pressure of 2 bar.

Lattice plane imaging in ZTA ceramics

Crystal Research and Technology, 1988
AbstractCharacteristic interface phenomena have been studied in zirconia toughened alumina (ZTA) using high‐resolution electron microscopy. Glassy phases in grain triple junctions, microstructure of interfaces between martensitic twins, regularly spaced misfit dislocations at the interface between intragranular t‐ZrO2 and the Al2O3 matrix and ...

Structure and properties of ZTA composites for joint replacement

AIP Conference Proceedings, 2017
The different approaches to the bone defects reconstruction with the use of ceramic materials have been developed recently. Ceramics are identical to the organic bone matrix by the type of chemical bond. The presence of osteogenesis on the surface and inside the pores depends on numerous factors such as the volume of pore space, size, shape of pores ...

Fluorescence and time-resolved spectra of ZTA ceramics

Journal of Physics and Chemistry of Solids, 1997
Abstract Two sets of high density zirconia-toughened aluminas (ZTA) are investigated by photoluminescent techniques. The luminescence response of the ceramics can be understood primarily on the basis of a mixed luminescence from the zirconia and alumina components.
