Fraunhofer Institute for Material and Beam Technology

Sandblasting at the speed of light: Fraunhofer IWS uses high-energy light instead of sand grains to clean and roughen – for example the surface of brake discs. For this purpose, researchers developed a laser-based process that realizes cleaning and structuring tasks significantly faster than conventional processes and should result in lower operating costs in series production.
