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

Formation of a Low-Porosity Bonding Layer with Enhanced Adhesive Strength via Gas-Thermal Spraying

Metals
Thermal barrier coatings (TBCs) are an effective means of providing thermal insulation and protecting the hot-section components of gas turbine engines. Their quality and performance characteristics largely depend on the microstructural features and the ...

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.

Preparation of barium hexaferrite coatings using atmospheric plasma spraying

, 2009
Thick coatings of barium hexaferrite with the compositions BaFe12O19 and BaCoTiFe10O19 were prepared using atmospheric plasma spraying (APS)technology. The coatings were prepared from pre-reacted powders of the desired composition.

Eu3+ as a structural probe in yttrium silicates through photoluminescence emission spectra

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract This work presents the first steps in using Eu3+ as a structural probe using photoluminescence (PL) emission spectra. The sol–gel synthesis of four Eu3+‐doped powders encompassing seven phases of the yttrium silicate phase system is detailed.

MICROSTRUCTURE CHARACTERISTICS OF DETONATION GUN SPRAYED CoNiCrAlY COATINGS

Havacılık ve Uzay Teknolojileri Dergisi, 2016
Overlay coatings are often chosen from the MCrAlY family of alloys. Overlay coatings are deposited by methods such as atmospheric plasma spraying (APS), high velocity oxy-fuel spraying (HVOF) and cold gas dynamic spraying (CGDS).
