Ablation‐Immune Thermal Armor Via Microstructural‐Compatibility Design for Extreme Thermal Conditions

Advanced Science, EarlyView.
This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Engineering Borophene Band Structure Through Thickness

Advanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...

THE INFLUENCE OF BORIDING ON THE PROPERTIES OF CEMENTED CARBIDES [PDF]

, 2020
Sintered carbide boriding is used either to form interlayers to increase the adhesion of deposited diamond layers to them by chemical vapor deposition (CVD) or to form layers on machine tools, which are then used without further processing in machining ...

The effect of the borosintering process in iron-based materials on abrasive and sliding wear

Revista de Metalurgia
Boriding is usually performed separately after sintering in powder metallurgy methods. In the borosintering process, sintering and boriding processes are carried out simultaneously. This saves energy as it shortens the heat treatment time. Additionally,
