How NiAlCoCrSiY Alloy Powder Enhances High-Temperature Coating Performance

Published by HUAXIAO TECH manufacturer

NiAlCoCrSiY alloy powder is widely recognized for its excellent oxidation resistance and thermal stability. This makes it an ideal material for high-temperature protective coatings in aerospace and energy sectors.

Outstanding Oxidation and Corrosion Resistance

NiAlCoCrSiY is a multi-component alloy combining Nickel (Ni), Aluminum (Al), Cobalt (Co), Chromium (Cr), Silicon (Si), and Yttrium (Y). This unique composition provides:

• Formation of a stable aluminum oxide (Al2O3) layer, preventing further oxidation

• Improved resistance to corrosive environments at elevated temperatures

• Enhanced adhesion to substrates due to the presence of Yttrium

These features make it perfect for turbine blade coatings and heat exchangers.

Exceptional Thermal Stability and Mechanical Strength

The alloy maintains its microstructure and mechanical integrity under prolonged exposure to high temperatures, ensuring:

• Reduced thermal fatigue and creep

• Sustained coating performance even above 1000°C

• Improved lifetime of critical engine components

Ideal for Thermal Spray and Additive Manufacturing

The powder’s spherical morphology and controlled particle size distribution ensure:

• Excellent flowability and coating uniformity during plasma or HVOF spraying

• Consistent melting and bonding in additive manufacturing processes

• High density, crack-resistant coatings

Application Scenarios

• Gas turbine blade coatings

• Aerospace engine components

• Industrial heat exchangers

• Power plant boiler parts

Benefits Summary

• Superior oxidation resistance at high temperatures

• Enhanced coating adhesion and durability

• Thermal stability for prolonged service life

• Excellent processing properties for thermal spraying and AM
