Flame Spray offers a complete range of diffusion coatings including platinum aluminide and si-modified aluminide. Protect your engine components, turbines, fuel cells, and more with our high-quality coatings.
Our Platinum aluminide (PtAl) coatings provide exceptional protection against oxidation at high combustion temperatures of up to 1,100°C. For more affordable options, our Si-modified aluminides are effective at lower temperatures.
And if flexibility is what you're after, our standard aluminides are widely used and trusted.!
What is Diffusion coating?
Diffusion coatings, specifically aluminide diffusion coatings, are extensively used in various industries to enhance the performance and durability of metal components
These coatings involve the diffusion of aluminum into the surface of a metal substrate, resulting in the formation of a protective layer. Overall, these coatings play a crucial role in ensuring the reliability and efficiency of various industrial applications.
Flame Spray offers different kinds of diffusion coatings:
- Si-modified Aluminides
- Standard aluminides
Platinum aluminide (PtAl) coatings are highly efficient to protect engine components against oxidation and the effects of combustion temperatures up to approx. 1,100°C. Si-modified aluminides are affordable and effective alternatives for the protection of turbines, fuel cells, boilers components up to approx. 900°C
Standard aluminides are widely used thanks to their flexibility. They are commonly used to protect the internal cooling passages and external surfaces of airfoils of Gas Turbines components, burners, fuel cells, nuts, bolts , etc. up to approx. 950°C.
Flame Spray proprietary technologies are applied on components of different geometry, dimensions and materials.
Advantages of Diffusion coating
One of the primary advantages of aluminide diffusion coatings is their ability to significantly increase the lifespan and performance of critical components in high-temperature environments.
The protective layer formed by the coating reduces the degradation caused by oxidation and corrosion, ultimately extending the service life of the coated parts. Additionally, aluminide diffusion coatings can improve the overall efficiency and reliability of gas turbine engines by reducing fuel consumption and minimizing maintenance requirements.
