ULTRA LOW FRICTION FILMS FOR WEAR REDUCTION

Characteristics of Diamond-Like Films Produced by Ion Beam Technique

• Extremely Low Coefficient of Friction : < 0.1 in Dry Nitrogen, Humid Air, Water and Ultra High Vacuum
• Extremely Low Wear Rate : < 10^-6mm³/Nm in Dry Nitrogen, Humid Air and Water
• Low Temperature Process Coating :< 100^oC
• Optically Smooth Surface:< 2 A Ra, RMS
• Chemically Inert: Against all Organic Solvents, Acid and Base at Ambient Temperature
• Ultra Hard ~ 15 GPa
• Excellent Adhesion on Various Materials: Metals, Alloys, Ceramics, Composites, Polymers and Optical Window Materials
• Thermal Stability: -50^oC to 250^oC

Potential Commercial Uses

• Self-lubricating, wear-resistant barriers for many types of moving mechanical assemblies: valves, seals, bearings, gears, disc, blades, medical implants and biodevices, jet-nozzles, guides, computer disk coating
• Solid-film lubricant for ceramics such as SiC, Si3N4 and Al2O3
• Cost-effective high performance coatings: composites aircraft skins, radar dome, casing skins, release agents, optical devices, fibers, mirrors, chemical Protestants, erosion/corrosion Protestants, tool inserts and antireflection coating
