FCVA Coating Technology

Nanofilm is a leader in Filtered Cathodic Vacuum Arc (FCVA) Technology

Filtered Cathodic Vacuum Arc (FCVA) Technology

Our Core Vacuum Technology – Filtered Cathodic Vacuum Arc (FCVA) is an international recognized technology. It’s 100% plasma based and offer many advantages.

FCVA Enables Highly Adjustable Coatings

FCVA enables highly adjustable coatings for optimal Diamond and Graphite-like properties, enables dense and uniform coatings

  • Curved Magnetic Field Only Lets High-energy Ions Pass

    - Non-ionised particles trapped in bend enabling pure ion deposition

  • Form Optimal Diamond and Graphite-like Properties

    - sp3 diamond structure provides hardness
    - sp2 graphitic structure provides conductivity

  • High Energy-Ions Provide Unique Advantages

    - More dense, uniform film – better corrosion resistance
    - Superior coverage
    - Strong adhesion

FCVA is Superior to Other Vacuum Coating Technologies
