CVD, CCDia MultiSpeed coating based on polycrystalline diamond

CCDia MultiSpeed is a coating obtained through CVD Hot Filament, HT- CVD. CCDia MultiSpeed  has the polycrystalline diamond properties obtained in form of multilayers with excellent adherence on top of hardmetal (*). This coating is specially recommended for mechanizing tools of carbon fibre, reinforced plastics with CFRP fibres and Al-CFC-Ti sandwiches used in aeronautic industry.

Benefits of the coating CCDia MultiSpeed

  • Alternated structure between Micro-PCD and nanocrystalline multilayers.
  • High hardness and resistance to abrasive wear.
  • Avoids cold micro-solder.
  • Excellent adherence with contents of cobalt up to 10%.
