Coating types    
    There are three main kinds of carbon films:
  • Plasma polymer films
    with a polymer-like chain structure consisting of carbon and hydrogen atoms

  • Amorphous carbon films (DLC)
    with a crosslinked, random arrangement of atoms; in addition to carbon they mostly contain not only hydrogen but also in some cases additional elements for modifying coating properties

  • Crystalline carbon films
    consisting of crystalline carbon with a regular atomic structure and only a very minor amount of impurities. Depending on whether the crystal lattice is graphite or diamond a distinction is made between
