Welcome to Diffusion Alloys...

We have been supplying diffusion coating services for over sixty years. In 1955, Diffusion Alloys was the first company in the world to launch chromising as a commercial industrial diffusion coating process.

Our mission is to protect and extend the life of our customer's products with diffusion coatings. With over 60 years of embedded knowledge, we develop and apply highly effective diffusion coatings that protect against metal degradation.

We are at the forefront of applications for clean energy and the hydrogen industry. We develop our coatings and processes to meet the needs of a greener future. Our staff are inquisitive, develop, test, and improve. Together we drive our business forward to meet the global challenges ahead.

We offer a range of diffusion coatings to protect against metal and systems degradation caused by high temperature corrosion, chromium leech, metal dusting, sulfidation, oxidation, hydrogen permeation, wear and abrasion.

We design our diffusion coatings to produce the best protection possible and can tackle complex, intricate and large scale components.
