Alleima, a global manufacturer of high-quality advanced stainless steel and specialty alloys, industrial heaters, is investing in thermal spray technology. Thermal spraying enables coatings with specific properties that are crucial for improving products such as electrolyzes for the production of green hydrogen. Green hydrogen, produced by the electrolysis of water using renewable energy, plays a central role in the transition to a carbon-free economy. Thermal spraying enables the development and industrial production of key components in an electrolysis stack.
The technology will eventually make it possible to develop products that replace expensive material solutions. This will help to reduce the cost of electrolyzer stacks, which in turn can promote the increased use of green hydrogen and thus reduce carbon emissions. The process uses a heated material in powder form that is propelled at high speed onto the surface to be coated. When the powder lands on the surface, the powder particles deform and solidify. Typically, multiple layers are sprayed onto the surface to achieve the desired properties.
