Unlock the Full Potential of Your Components with Diffusion Alloys

At Diffusion Alloys, we specialise in surface coating technologies designed to extend the life, durability, and performance of industrial components, even in the harshest of conditions. Whether it’s high temperatures, corrosive environments, or mechanical wear, our cutting-edge diffusion coatings provide unmatched protection. If you’re in an industry where reliability is critical—such as energy, automotive, or oil & gas—our advanced coating solutions could be just what you need.

Our Core Technology: Diffusion Coating

At the heart of what we do is the diffusion coating process. Unlike traditional coatings that can wear away or chip over time, diffusion coatings embed protective elements like aluminium, chromium and boron directly into the surface of metal components. This creates a tough, durable layer that not only protects against oxidation, corrosion, and wear but also becomes an integral part of the component itself.

Our flagship offering is aluminising, which involves infusing a layer of aluminium into the surface of a component. This forms a robust aluminium oxide barrier when exposed to air or high temperatures, making it an ideal solution for extreme environments, such as high-temperature gas turbines. We also offer other diffusion coatings, including chromising depending on your specific needs.

Tailored Solutions for Diverse Industries

Our diffusion coating solutions are trusted across a wide range of industries, providing essential protection for components operating in some of the most demanding environments.

Oil & Gas

Operating in the oil and gas industry means exposure to extremely corrosive environments, whether offshore or on land. Components such as pipelines, valves, and drilling equipment face constant threats from hydrogen sulphide (H₂S), carbon dioxide (CO₂), and other aggressive substances. Our corrosion-resistant coatings offer essential protection, reducing the risk of component failure and costly repairs.

Energy and Power Generation

The extreme thermal and mechanical stress seen in gas and steam turbines can severely limit the lifespan of unprotected components. Diffusion Alloys’ coatings safeguard critical parts like turbine blades and vanes from high-temperature oxidation and corrosion, helping to reduce downtime, minimise maintenance costs, and improve overall system efficiency.

Automotive

In high-performance automotive applications, where engines experience intense heat and pressure, components like turbochargers, exhaust manifolds, and pistons are vulnerable to thermal fatigue and oxidation. Our coatings give these parts the heat resistance they need to perform at their best, extending their service life and boosting vehicle efficiency.

Why Choose Diffusion Alloys?

• Enhanced Durability: By embedding protective elements directly into the component’s surface, we offer long-term protection against oxidation, corrosion, and wear.
• Heat Resistance: Our coatings are designed to withstand extreme temperatures, making them perfect for aerospace, power generation, and automotive applications.
• Reduced Maintenance and Downtime: Coated components last longer and require less maintenance, saving you both time and money.
• Customised Solutions: Every industry and application is different. We work closely with our clients to develop coatings tailored to their specific needs, ensuring optimal protection and performance.
