Vacuum Arc Thin Film System

The Industrial Vacuum Arc Thin Film System utilizes cathodic arc evaporation to deposit dense, highly adherent metallic, alloy, and ceramic thin films. A high-current, low-voltage arc vaporizes solid cathode materials into a highly ionized plasma stream (40% - 80% ionization rate), ensuring exceptional film-to-substrate bonding strength and high deposition rates.

Engineered for industrial production and advanced materials research, the platform integrates multi-cathode configurations, precision reactive gas management, and automated process control for industrial coatings such as TiN, TiAlN, CrN, and DLC.

High Plasma Ionization: Cathodic arc ionization (40% - 80%) promotes dense film nucleation, eliminating columnar microstructure defects.

Enhanced Adhesion Strength: In-situ high-energy ion cleaning achieves critical scratch loads (Lc) exceeding 40 N on tool steel (ASTM C1624 verified).

Toroidal Magnetic Filtration (Optional): Deflects plasma trajectories to trap and eliminate macro-droplets, producing defect-free smooth nano-coatings.

Closed-Loop Reactive Control: Mass flow controllers (MFCs) precisely regulate N2, O2, C2H2, and Ar for stoichiometric compound deposition.

Rapid Maintenance: Quick-release cathode assembly allows target replacement within 30 minutes.

Roughing & Roots Stage: Direct-drive rotary vane and mechanical booster pump for rapid drawdown to 10 Pa.

High Vacuum Stage: Oil diffusion pump with liquid nitrogen cold trap or magnetically levitated turbomolecular pump (1600 L/s) reaching < 5 x 10^-4 Pa.
