Degradation behavior of magnetron sputtered Cr/CoAlTa/YSZ nanostructured coating on nickel super-alloy
To improve Superni-718's oxidation resistance at high temperatures, a nanostructured Cr/CoAlTa/YSZ multilayer coating was deposited by magnetron sputtering. The effects of substrate deposition temperatures (100°C, 150°C, and 200°C) on the coating microstructure, phase stability, and oxidation kinetics were systematical...
