Alleima takes over thermal spray technology to support the green transition

Alleima, headquartered in Sandviken, Sweden, reports that it was invested in new thermal spray technology. The company aims to develop new products in the field of sustainable energy, where it can be used for the production of green hydrogen, for example. The company said it was in dialogue with several customers, whereby the first prototype of the coated material has already been sent for evaluation.

The thermal spray is an advanced manufacturing method in which material is melted into powder or wire shape and sprayed onto a surface to create a coating with specific properties. The technology enables coatings with specific properties that are of crucial importance for the improvement of products such as electrolysirs for the production of green hydrogen. Green hydrogen generates a central role in the transition to a carbon-free economy using the electrolysis of water using renewable energies. The thermal spray enables the development and industrial production of key components in an electrolysis stack.

“This investment is part of the company's long -term strategy to promote innovations and create sustainable solutions. It is a pilot that is mainly used for research purposes, but is also used for the production of small measures. If possible, we can offer this technology in our manufacturing processes, but can meet advanced materials and components that meet the high requirements of hydrogen production. Tom Eriksson, Head of Strategic Research at Alleima.

Alleima assumes that the thermal spray technology of adoption will ultimately enable products to develop products that replace expensive material solutions, which reduces the costs for electrolyser stacks and thus reduces carbon emissions by the increased use of green hydrogen. The process uses a heated material in powder form, which is driven to the surface to be coated at high speed. When the powder ends on the surface, deform and solidify the particles. Typically, several layers are sprayed on the surface in order to achieve the desired properties.

“This is further proof that Alleima continues to be at the forefront of innovation and technical development. Our goal is to create groundbreaking solutions for a cleaner and greener world. We are currently in contact with several potential customers that test our prototype in their test options,” added Mikael Blazquez, EPP and Head of Strategy, M&A and IT and IT.

One of the advantages of thermal sprays is that it is a fast process and can be used in many different areas, depending on the basic material used. Common materials include metals, metal alloys, composite materials and ceramics. These coatings can withstand high temperatures and protect components from wear and corrosion, which makes them ideal for industrial applications. The coatings can also improve the properties of the component (e.g. friction, electrical conductivity or insulation).
