Ni 21Cr 9Mo 4Fe 4(Nb / Ta) 0.4Al 0.4Ti Powder Applications:
1. Protective Barriers: It is used as a protective barrier coating in environments subjected to high temperatures and corrosive conditions, such as in gas turbines, industrial furnaces, and other high-temperature industrial processes.
2. Bond Coats for Thermal Barrier Coatings: It serves as a bond coat for ceramic thermal barrier coatings in aerospace and power generation industries, enhancing the adhesion of ceramic top coats to metal substrates and providing an intermediate layer that mitigates thermal expansion differences.
3. Oxidation and Corrosion Resistance: Its application extends to components exposed to oxidative and corrosive environments, such as turbine blades, combustion liners, and exhaust components in both aerospace and automotive industries.
4. High-Temperature Applications: The powder is suitable for applications requiring materials that maintain their integrity and performance at temperatures up to 980°C (1800°F), such as in heat exchangers and other high-temperature equipment.
5. Flexibility-Dependent Uses: Due to the formation of a ductile Al2O3-Y2O3 complex ceramic oxide, it is ideal for applications where mechanical flexibility and high-temperature cohesive strength are important, such as in flexible joints and dynamic components exposed to thermal cycling.
