General Industrial
Diffusion Alloys offers wear resistant diffusion coatings for industrial applications. Our deep knowledge base and over 60 years of experience makes Diffusion Alloys a global specialist in protective coatings for wear resistance
Boronizing
Boronizing, sometimes referred to as boriding, is a diffusion coating with a low co-efficient of friction that is capable of retaining its high hardness at elevated temperatures.
Diffusion Alloys are capable of boronizing a wide range of metal base layers including nickel, cobalt, tungsten carbide and most ferrous alloys without sacrificing the corrosion-resistance or mechanical properties of the base material. Boronizing is used in a wide range of applications and industries. It is commonly used to produce glass bottle moulds, plungers, dies, tooling and for components in the oil & gas and turbomachinery industries.

Chromizing
Diffusion Alloys was the first company globally to launch chromizing as a commercial industrial diffusion process. With 60 years of experience in applying chromide coatings we working closely with our customers to provide specified or customised chromide coatings that satisfy specific requirements for wear and/or corrosion resistance.
Chromide coatings are used on a wide range of components, including chain pins, sprags, levers, rods, locators, seals and tubes.

Aluminizing / Calorizing
Aluminizing and calorizing by Diffusion Alloys infuse aluminium into materials, fortifying against corrosion. Originating in Tyco Van Aller’s 1911 patent, these processes, including Alonizing™, enhance steel and alloy longevity. Diffusion Alloys (DA) leads pack aluminizing, crucial for resisting metal dusting, carburization, oxidation, and sulfidation. Process versatility accommodates various substrates, ensuring reliability through stringent quality control measures.
