Role of suspension preparation in the spray drying process to obtain nano/submicrostructured YSZ powders for atmospheric plasma spraying [PDF]

, 2015
Thermal barrier coatings were manufactured by atmospheric plasma spray process from YSZ powders. These powders were made by a reconstitution process which consists in a spray-drying of suspensions followed by thermal treatment of the granules.

Investigations of microstructure and selected mechanical properties of Al2O3 + 40 wt.% TiO2 coatings deposited by Atmospheric Plasma Spraying (APS)

Welding Technology Review, 2019
Atmospheric Plasma Spraying (APS) enables deposition of coatings from different materials, including those based on Al2O3 and TiO2. In this work, Al2O3 + 40 wt.% TiO2 coatings were tested. The relationships between mechanical properties, microstructure and spraying parameters (namely: spraying distance and torch scan velocity) were investigated ...

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

Advanced Optical Materials, Volume 14, Issue 2, 14 January 2026.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

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

Rare Metals, Volume 45, Issue 1, January 2026.
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

Interdiffusion kinetics of yttria and alumina

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The interdiffusion kinetics of yttria‐alumina diffusion couples produced by spark plasma sintering (SPS) were investigated at 1350°C, 1425°C, and 1500°C. The SPS diffusion couples were heat‐treated in air at their sintering temperatures for 0, 24, and 96 h.
