Enhanced Thermal Shock Resistance of Ceramics through Biomimetically Inspired Nanofins

open access: yes, 2010
We propose here a new method to make ceramics insensitive to thermal shock up to their melting temperature. In this method the surface of ceramics was biomimetically roughened into nanofinned surface that creates a thin air layer enveloping the surface ...

UNIFIED THERMAL SHOCK RESISTANCE OF ULTRA-HIGH TEMPERATURE CERAMICS UNDER DIFFERENT THERMAL ENVIRONMENTS

open access: yes, 2014
The thermal shock resistance (TSR) of the ultra-high temperature ceramic (UHTC) plate under convective environments is studied. The critical failure temperature difference has a danger temperature range about the thermal shock initial temperature ...

Crucial effect of SiC particles on in situ synthesized mullite whisker reinforced Al2O3-SiC composite during microwave sintering

open access: yesProcessing and Application of Ceramics, 2017
Mullite whisker reinforced Al2O3-SiC composites were in situ synthesized by microwave sintering at 1500°C for 30min. The influence of SiC particle size on heating process and properties of Al2O3-SiC composite were investigated. The XRD and SEM techniques

The Mechanism of High Thermal Shock Resistance of Nanostructured Ceramic Coatings

open access: yes, 2015
The nanostructured and the conventional ZrO2 coating samples were thermal shocked at a series of temperatures. The elastic modulus and the hardness of two kinds of coatings were investigated by the nanoindentation tests.

Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

Titania Effect on Sintering behavior of Alumina

open access: yesمجلة بغداد للعلوم, 2009
The sintering behavior of Alumina was investigated by adding TiO2. The addition of TiO2 lowered the sintering temperature of the Alumina compared with those of pure Alumina.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
