The IWS developed amorphous carbon coatings (Diamor®) are exceptionally useful as protective coatings. Films of a wide thickness range are deposited achieving excellent adhesion and performance. The synthesis process operates at low temperatures in a vacuum environment with a special pulsed arc process. IWS engineers collaborate with industrial partners to commercialize Diamor® coatings and the associated coating machine technology. As part of this portfolio we have developed the unique thin film testing technique LAwave, which is applied for coating optimization and quality control.
