Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content

open access: yesPlasma Processes and Polymers, EarlyView.
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

open access: yesRare Metals, EarlyView.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Enhancing the Ionic Conduction of Ceria‐Based Electrolytes for LT‐SOFCs via Entropy Engineering

open access: yesRare Metals, EarlyView.
ABSTRACT Developing alternative electrolytes with enhanced ionic conductivity is crucial to reducing the operating temperature of solid oxide fuel cells (SOFCs) for broader applications. Entropy engineering offers many opportunities for material design, presenting a promising avenue to develop new electrolytes.

Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

open access: yesRare Metals, EarlyView.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and
