Surface modification for mechanical engineering at the Fraunhofer FEP

Optimized surfaces are the basis for a lot of innovation in the machine building sector. Layers that make products and components resistant to corrosion, wear, and scratching have enormous commercial importance. Indeed, the damage caused by corrosion alone amounts to billions annually. Layers having reduced friction also make a significant contribution to lowering energy and material consumption.

Using sputtering technology, plasma-activated high-rate deposition and high-rate PECVD, Fraunhofer FEP develops highly efficient vacuum processes and technologies to clean surfaces and components and to improve their properties via deposition of a wide variety of layers and layer systems. Together with the Fraunhofer Cleaning Technologie Alliance we offer a broad portfolio of surface cleaning technologies.

We use electron beams as a versatile tool to weld components, cure surfaces, or customize properties. The scaling up of processes under near-industrial production conditions is a key aspect of our work.
