SUCASLIDE® - The modern friction-reducing DLC coating

SUper CArbon SLIDE (SUCASLIDE® DLC Coating) is a metalliferous, amorphous carbon coating (a-C:Me) from voestalpine eifeler. This PVD coating displays all the benefits of a modern, friction-reducing coating:

  • Good adhesive strength
  • Very hard
  • Sufficient coating thickness (approx. 2 µm)
  • Low friction coefficient /anti-friction coating
  • Very dense and smooth coating structure
  • Biocompatible


  • Forming and cutting tools for non-ferrous metals, in particular aluminum (e.g. IHU)
  • In case of injection molds, both for the mold surfaces and for sliders and ejectors (absolute dry running possible)
  • Combination with other PVD and CVD layers possible
  • Precision components, motor and gear parts, gears, storage and valve parts, sealing and guiding elements
  • Paper knives, industrial blades
  • Saw blades for composite materials
  • Components of food-, vacuum- and cooling technology (dry running)


  • Significant improvement of the slide characteristics with respect to traditional PVD layers (also with minimal lubrication a significant improvement results), decrease of adhesion and both friction partners are protected
  • Improvement of the run-in characteristics with tools and precision components
  • Improvement of the emergency running characteristics
  • Suited for low-tempered steels (case hardened, spring and bearing steels)
