Heraeus broadens the application range of the Aerosol Deposition coating method. So far, the technology, which was developed in Japan, has been used mainly in Asia for coating of components for plasma etch chambers. Although the coating method offers many advantages, other industries have hardly applied it until now. "However, feasibility studies by universities such as the University of Bayreuth have shown that Aerosol Deposition offers advantages also for other applications," Dr. Ilka Luck says, Head of Heraeus High Performance Coatings. She sees potential in sensor technology, power electronics, battery, and medical technology, among others.
"We have worked intensively over the past two years on optimizing processes and machines for production on industrial scale. As a result, we are the only supplier that accompanies customers all the way from feasibility study to series production," Luck comments. The technology is particularly promising when conventional methods do not achieve the required quality, or the desired coating cannot yet be produced at all.
Aerosol Deposition is a process for producing thin material layers. Material particles are accelerated to a speed of several hundred meters per second with the aid of a carrier gas. These then hit a surface, the so-called substrate, where they form a closed film.
