• 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
