VDI 2840:2020-09

The standard deals with typical characteristics of modern coatings from carbon, which are deposited with the procedures of chemical or physical vapour deposition (CVD or PVD). Focal point is a classification of all carbon films, which organizes the different film types on the basis of their physical and chemical properties. The standard includes a uniform classification and nomenclature especially for amorphous carbon films (DLC) and diamond films. This allows the potential user of coated workpieces and tools to pre-select suitable carbon film types. A characterizing part refers to the important properties of the individual film types that are manufactured industrially today.
