Mechanism of depositing NiCrAlY coating of high tensile adhesion by surface-oxide-free droplets during atmospheric plasma spraying on smooth Nickle-based superalloy

Key Points

• Enhanced adhesion observed in nickel-based superalloys with NiCrAlY coatings.
• Significant reduction in surface oxide layers improves coating integrity and performance.
• Atmospheric plasma spraying technique utilized for effective deposition of coatings.
• Implications include potential for better durability in high-temperature industrial applications.
