DLC Coating stands for diamond-like carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance.

DLC coatings can have different structures and properties that rely on the ratio of SP3 (diamond) and SP2 (carbon) or other fillers like hydrogen, silicon, and metal in the layer.

  • High hardness
  • Low coefficient of friction (0.02 - 0.15)
  • High corrosion resistance
  • Great adhesion to substrate material
  • Fretting resistance
  • Adhesive wear resistance
  • Self lubrication in dry wear conditions
  • Excellent release properties
  • Electrical insulation

Properties Unique to CeraTough™-D:

  • Capable of achieving high thickness (up to 30µm)
    • By comparison, typical DLC coatings have a thickness of 1-2 microns, making them poor as an application against heavy abrasion or corrosion
  • Non-line-of-sight PACVD technology allows us to DLC coat internal surfaces and complicated shapes with very high accuracy without manipulating the parts
  • Capability of duplex coatings: Ion Plasma Nitriding and DLC can be combined into one cycle
  • Excellent surface finish will mirror that of the substrate

Application Methods:

  • Cathodic Arc Physical Vapor Deposition (PVD) with elements of CVD
  • Plasma Assisted Chemical Vapor Deposition (PACVD)

Size Capabilities:

  • CAPVD systems have a 500 lb. weight limit and can accommodate parts 30" x 20" x 20" in size
  • PACVD systems have an 18,000 lb. weight limit and can accommodate parts 60" in diameter and 83" tall

Common Applications:

  • Cutting tools for aluminum, aluminum-silicon alloys, powder metallurgy alloys
  • Tools for metal forming and blanking
  • Plastic molds and extrusion components for abrasion and corrosion resistance, good release, and antibacterial properties
  • Hydraulic components – cylinders, pistons, gear pumps
  • Valve components – balls, gates, seats, actuators, housings
  • Automotive components – crank shafts, cam shafts, gears, bearings, piston rings, tappets, wrist pins, fuel injectors
  • Pump components – impellers, diffusers, rotors
  • Mechanical seals
