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

Rare Metals, EarlyView.ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy
