DLC is an innovative carbon-based coating with wide spectrum of application which allows you to deal with problems related to abrasion, to chemical attack and sliding.

The low deposition temperature , the hardness and the low coefficient of friction make it of extreme interest.

It is applied on finished parts while maintaining the state of the surface finishing.

The DLC is deposited by the PA-CVD (Plasma Assisted – Chemical Vapour Deposition) technology which allows to maintain low temperature of depositing and at the same time ensures an excellent adhesion.


The high hardness and low friction coefficient arise from the simultaneous presence of sp2 hybridized Carbon (Graphite) and sp3 (Diamond).
It works very well for dry contacts.


  • High hardness (resistance to abrasion and wear)
  • Low coefficient of friction(smoothness and anti-adherence)
  • Excellent chemical inertia (resistance to corrosion and chemical attack by acids, bases and salts)
  • Compactness(impermeabletogases,suchastoHydrogen)
  • Electrical insulation
  • Biocompatible


  • Steel, ferrous alloys in general
  • Aluminium and its alloys
  • Titanium and its alloys
  • Copper and its alloys (bronze, Cu -Be)
  • Tungsten Carbides
