Black & grey A-DLC coatings


Especially developed for internal components and casings

A-DLC (Amorphous Diamond-like Carbon) treatment has been developed to combine excellent working performance with a high esthetic level.


This hybrid production technology “PV-PECVD” allows a very esthetic black or anthracite layer which also has the essential mechanical properties: wear resistance, chemical resistance, low coefficient of friction.

The coating deposition temperature is less than 100°C.

The deposit thickness is 3µm +/-0.5

HV 0.05 hardness is between 1500 and 1800

Conforms to REACH and RoHS standards


Deep black and anthracite colorized coatings

  • Cases

  • Crowns
  • Movement parts
  • Screws
  • Etc

The advantages

  • Excellent quality for money
  • Excellent results in watchmaking tests (climatic resistance, UV, etc.)
  • Deep black or anthracite color
  • A-DLC can be deposited on all substrates (copper alloys, titanium, gold, steel and stainless steel, plastics)
  • Wear resistant
  • Clean deposit
  • Good compromise between ductility and hardness
  • Homogeneity and reproductivity of the color
  • Homogeneity and reproductivity of thickness
  • Environment and UV resistant
  • Low temperature procedure
  • Respect of terminals
  • Biocompatible
  • An A-DLC treated part can be detreated and retreated

  • Surcotec
