Filtered Cathodic Vacuum Arc
• FCVA is based on Cathodic Vacuum Arc
• Especially, it has a bent duct and electromagnetic coils
between cathode and workpiece in order to deposit smooth coatings
• Effective area : Φ450 x H400
• Deposition rate, 0.15 um/h per cathode with double rotation
• Etching source : Ion Gun •Buffer layer source : Sputter
• H Free DLC : FCVA gun x 4
• Pumping : R/P+MBP+Turbo Pump ~10-5 torr
• Heater : <250℃
ta-C Coating
● Tetrahedral amorphous Carbon
● Hydrogen free coating
● Higher sp3(diamond) bonding
● Hardest coating of DLC ,<80GPa (HV2,000~7,000)
● Thermal stability ,<500℃
● Low friction, 0.2@dry
● Typical thickness : <1um for tools , 1~10um for auto. parts
