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.
