Other coatings

Vacuum deposition and particularly Physical Vapour Deposition (PVD) make it possible to deposit in a thin layer all metals, alloys and compounds available in sheet plate form, on metals, alloys, glass, ceramics, polymers, composites, etc. The applications of these techniques are very diverse: optical, electrical, thermal, anti-wear, friction, decoration, etc. The HEF Group has developed various treatments implementing these techniques and materials to meet the most diverse requirements:
 
  • VACUUM DEPOSITION FOR DECORATIVE USE 
 
The TS™ CHROMIUM coating is produced by magnetron cathode spraying. It deposits on large parts special metal alloys or metals, producing decorative layers.
 
Characteristics:
  • Chromium, stainless steel, gold, etc. appearance
  • Large diversity of materials depositable: chromium, aluminium, gold, etc. or specific alloys to specifications
  • Very great purity of coatings
  • Control of thicknesses and of surface finishes
  • Resistance to chemical attacks (according to filler materials)
 
Remarks:
Application on large parts.
 
Materials which can be treated:
Glasses - Plastics - Organic matrix composites - Ceramics - Cermets - Metals and alloys - Logos - etc.
 
Examples of application:
Signs
 
 
  • VACUUM DEPOSITION FOR CORROSION PROTECTION: CORRALU™ V
 
CORRALU™ V is a 10 to 50µm pure aluminium deposit giving the part treated electrical continuity and corrosion protection properties.
 
Characteristics:
  • corrosion protection
  • electrical continuity
 
Materials which can be treated:
Steels - Stainless steels - Aluminium alloys - Refractory alloys - Titaniums - Any metal compatible with vacuum deposition - Application possible on plastics, glasses and ceramics
 
Remarks: 
Dimensions from 1 cm to 2 m. Over 2 m, contact us
Possibility of complementary treatment (SiOx, chemical conversion, Surtec 650, Corralu, varnish, cetyl alcohol)
 
Examples of application:
Fighter aircraft structural parts - screws, nuts, bolts, etc. - Aeronautics - On-board electronic units - Sensor supports - Connector bodies - etc.
 
 
 
  • VACUUM DEPOSITION FOR OPTICAL USE
 
Coatings by magnetron cathode spraying of special metal alloys or metals, producing layers with reflective or semi-transparent properties, suited to the various ranges of wavelengths.
 
Characteristics
