FCVA Coating Technology

NTI Nanofilm leader in Filtered Cathodic Vacuum Arc technology, enabling ultra-dense, low-friction, low particle coatings for sensitive applications.

Filtered Cathodic Vacuum Arc (FCVA) Technology

At the heart of NTI Nanofilm’s innovation is our Filtered Cathodic Vacuum Arc (FCVA) technology, a fully plasma-based process that creates ultra-dense ta-C coatings with exceptional purity, hardness, and adhesion. Engineered for particle-sensitive applications.

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 Filters Out Impurities for Particle-Free Coatings

    - Particles trapped in the bend enable pure high-energy ion deposition, forming cleaner and denser coatings.

  • Tunable Diamond-like and Graphite-like Structures for Optimal Performance

    - sp³ diamond-like bonds deliver exceptional hardness and wear resistance
    - sp² graphitic bonds enhance conductivity and lubricity for smoother performance

  • High Energy Ions Deliver Superior Density and Adhesion

    - Creates ultra-dense, uniform films with enhanced corrosion resistance
    - Provides uniform and controlled coating thickness across surfaces
    - Ensures strong adhesion for longer coating durability

FCVA is Superior to Other Vacuum Coating Technologies
