Ni 21Cr 9Mo 4Fe 4(Nb / Ta) 0.4Al 0.4Ti Powder Description:
Ni 21Cr 9Mo 4Fe 4(Nb/Ta) 0.4Al 0.4Ti powder possesses excellent high-temperature oxidation and corrosion resistance due to high molybdenum and chromium content. Structural stability and wear resistance are improved upon the addition of niobium or tantalum by promoting the precipitation of carbides and grain refinement. Aluminum and titanium, which help in the formation of stable intermetallic compounds, make this powder deliver superior high-temperature strength and toughness. Generally, it is more ideal to use in high-performance coating applications requiring long-lived coatings or components in extreme environments.

Ni 21Cr 9Mo 4Fe 4(Nb / Ta) 0.4Al 0.4Ti Powder Applications:
1. Protective barrier: Used as a protective barrier coating in high temperature and corrosive environments, e.g., gas turbines, industrial furnaces, and other high temperature industrial processes.
2. Thermal barrier coating bonding layer: It is employed as the bonding layer of ceramic thermal barrier coating in power generation and aerospace applications, enhances the adhesion of the metal substrate to the ceramic top coating, and provides an intermediary layer to reduce the thermal expansion difference.
3. Corrosion and oxidation resistance: It is used on components exposed to corrosion and oxidation environments, e.g., turbine blades, combustion gaskets, and exhaust parts in the auto and aerospace sectors.
4. High Temperature applications: The powder is used where the material must maintain its integrity and function at temperatures of up to 980°C(1800°F), e.g., heat exchangers and other high temperature equipment.
5. Dependent use flexibilities: Due to the availability of malleable Al2O3-Y2O3 composite ceramic oxides, it is best suited for application in situations where mechanical flexibility and cohesion strength at high temperatures are essential, i.e., in flexible joints and thermal cycling dynamic components.
