![In Laser-ArcTM systems a thin coating of just a few micrometers of tetrahedral amorphous carbon, abbreviated ta-C, is for example applied to piston rings. These coatings are very hard and after mechanical polishing, also very smooth.

Fraunhofer IWS develops technologies and systems for the industrial series production of drive and engine components as well as for their fast and cost-effective customized production and repair. Our portfolio ranges from laser-based processes such as laser beam welding and cutting to additive manufacturing processes and innovative adhesive bonding procedures for difficult-to-weld mixed joints. In addition, we offer various solutions such as friction-reducing coatings or laser surface treatment to protect engine as well as transmission parts from wear and tear while increasing their service life.
