Why AlCrTiNiY Alloy Powder Is a Top Choice for Oxidation-Resistant Coatings

Published by HUAXIAO TECH manufacturer

In high-temperature industries such as aerospace, metallurgy, and energy, oxidation resistance is vital for surface coatings and structural components. AlCrTiNiY alloy powder offers a powerful combination of thermal stability, surface adhesion, and corrosion resistance—making it an ideal material for advanced coating applications.

Advanced Oxidation and Corrosion Resistance

The unique elemental composition of AlCrTiNiY includes:

• Aluminum (Al) and Chromium (Cr) for forming dense, protective oxide layers

• Titanium (Ti) for enhancing structural stability and phase control

• Nickel (Ni) as a matrix to ensure toughness at high temperatures

• Yttrium (Y) to improve oxide layer adhesion and reduce spallation

This synergy significantly extends the service life of components under extreme oxidative environments.

Stable Performance in Extreme Environments

AlCrTiNiY alloy powder performs reliably in:

• High-temperature oxidizing atmospheres

• Thermal cycling conditions

• Environments with aggressive corrosive gases or molten salts

The alloy's microstructure ensures long-term phase stability, which is critical in thermal barrier coatings (TBCs) and hot-section parts.

Ideal for Thermal Spray and Additive Manufacturing

The powder’s fine, spherical morphology and controlled particle size distribution allow:

• Efficient feeding in plasma spray and HVOF processes

• Uniform deposition with strong adhesion

• Excellent compatibility with laser cladding or DED 3D printing methods

Application Scenarios

• Turbine blades and combustion liners

• Thermal barrier coatings for aerospace engines

• Heat shields and exhaust components
