FCVA

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


FCVA(图1)


• 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
