Plasma Process Revolutionizes Roller Bearing Steel Adhesion
Fraunhofer IST's innovative COAD process is revolutionising roller bearing steel adhesion. Since June 2024, the plant at Rohloff AG in Fuldatal has successfully used plasma instead of chemistry for reliable sealing material adhesion. This sustainable method is now being tested on a larger scale at the Fraunhofer Center for Circular Economy for Mobility in Wolfsburg.
The COAD process, developed by Fraunhofer IST, cleans and coats surfaces in one dry plasma process. This eliminates the need for chemicals, reducing solvent use and CO2 emissions. The process ensures better adhesion of sealing materials to roller bearing steel, enhancing the reliability of high-precision components, like those in bicycle drivetrains.
The joint project between Fraunhofer IST, Rohloff AG, and Tantec A/S has shown promising results. The process is versatile, working with various materials and component sizes. Now, it's being tested on a larger scale to explore its potential across different industries.
The COAD process, using plasma for better adhesion, is proving successful and sustainable. After initial success at Rohloff AG, it's now being tested at the Fraunhofer CCEM in Wolfsburg. With no specific personnel information related to a plasma project on bicycle drivetrains, the focus remains on the innovative process and its potential industry-wide impact.
