Diamond like coatings (DLC) are today one of the most often used coatings for improvement of mechanical frictional and tribological performance of many components and parts. The diamond like carbon term comprises different types of coatings or films whose structure is formed by amorphous carbon. Included as DLC coatings are also amorphous carbon films that contain small amounts of dopants such as metals. The DLC coatings are usually deposited either by Physical Vapor Deposition (PVD) or by Chemical Vapor Deposition (CVD), in some cases with plasma enhancement (PECVD). The typical thickness of the DLC films is in the range of several micrometers although some DLC films can be as thin as several tens of nanometers [3]. This application report summarizes the use of indentation, scratch, tribology and coating thickness measurements for a complete characterization of mechanical properties, adhesion and thickness of DLC coatings.
