Proto-TGO formation in TBC systems fabricated by spark plasma sintering [PDF]

open access: yes, 2010
Thermal barrier coatings (TBC) are commonly used in modern gas turbines for aeronautic and energy production applications. The conventional methods to fabricate such TBCs are EB-PVD or plasma spray deposition.

Atomistic Insights Into Lithium Alloying and Crystallization at Metal Interlayers in Zero‐Excess Lithium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Molecular dynamics simulations with machine learning potentials, combined with experiments, reveal how interlayer metals govern Li alloying and crystallization in zero‐excess lithium batteries. Mg and Zn promote solid‐solution alloy‐mediated pathways that influence Li diffusion and structural uniformity, while Bi forms ordered intermetallics with more ...

Beneficial Effect of Pt and of Pre-Oxidation on the Oxidation Behaviour of an NiCoCrAlYTa Bond-Coating for Thermal Barrier Coating Systems [PDF]

open access: yes, 2011
The oxidation behaviour of a thermal barrier coating (TBC) system is a major concern as the growth of the thermally grown oxide (TGO) layer on the bondcoating creates stresses that greatly favour the thermal barrier spallation.

Suppressing Dendrite Formation through Au‐Driven Interfacial Engineering for Solid‐State Lithium‐Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A thin gold nanolayer on lithium metal enables stable and uniform lithium plating in solid‐state batteries, enabling nearly 1 year and 11 months of continuous operation. The conductive coating lowers interfacial resistance, suppresses dendrite growth, and improves cycling stability, attributed to homogeneous deposition of Li+ on the gold layer ...

The effect of high-power transient events on tungsten and tungsten coatings used for radio frequency launcher applications [PDF]

open access: yesEPJ Web of Conferences
High-temperature plasma-facing material coatings used for radio frequency (RF) launchers need to be robust enough to survive RF breakdown arcing or other transient events from the plasma (e.g., an edge localized mode) without causing a catastrophic ...
