Flame Spray - Diffusion Coating

Diffusion coatings are advanced metal surface protection processes where elements such as aluminum are diffused into the substrate to create a protective layer. This layer prevents oxidation and corrosion, extending the life of metal components in high-temperature environments.

The diffusion process is particularly effective for protecting components of gas turbines, engines and other parts exposed to extreme conditions. These coatings provide a barrier of protection that allows components to maintain high performance and reduces the need for frequent maintenance.

Types of Diffusive Coatings Offered by Flame Spray

Flame Spray offers a complete range of diffusion coatings designed to protect critical components in high temperature applications such as engines, turbines and fuel cells.

1. Pt-Aluminide (PtAl) Coatings: Platinum aluminide (PtAl) coatings are ideal for protecting engine components from oxidation at high temperatures. These coatings maintain integrity and performance even under operating conditions up to 1,100°C, providing reliable and long-lasting protection.
2. Si-Modified Aluminides: Si-modified aluminide (Si-modified Aluminide) coatings are a more economical option for lower temperature applications, such as turbines and fuel cells. These coatings are highly effective up to temperatures of around 900°C, offering an excellent balance between performance and cost.
3. Standard Aluminides: Standard aluminide coatings are widely used due to their flexibility and reliability. They are ideal for protecting both internal cooling passages and external surfaces of components, such as gas turbine airfoils, burners and boiler components, up to temperatures of around 950°C.

Diffusion coatings offer a number of advantages, making them an ideal choice for components that must operate in extreme environments. Key benefits include:

• Resistance to hot oxidation: Pt-Al and silicon-modified aluminide coatings effectively protect against oxidation, preventing thermal degradation of the underlying metal.
• Resistance to hot corrosion: The protective layer created by aluminum reduces corrosion at high temperatures, improving the overall life of components.
• Increased durability: These coatings significantly extend the life of components, reducing the need for frequent maintenance and replacement.
• Improved operating efficiency: Diffusion coatings improve the efficiency and reliability of turbine engines, reducing fuel consumption and ensuring smoother, more continuous operations.

Diffusive coatings are used in a wide range of industries where high temperatures and extreme environmental conditions can compromise the life and performance of metal components. Key applications include:

• Power Generation: Gas turbines, burners, and other critical equipment.
• Transportation: Aircraft engines and other components subjected to high thermal loads.
• Fuel Cells: Components exposed to severe thermal cycling and chemically aggressive conditions.
