Multi-Arc PVD Thin Film Equipment

The Industrial Multi-Arc PVD System utilizes high-ionization cathodic arc physical vapor deposition to deposit dense, stoichiometric hard coatings (such as TiN, TiAlN, CrN, and DLC) onto metallic substrates. Engineered for high-volume contract coating centers and captive manufacturing lines, this system optimizes wear resistance, friction reduction, and thermal stability for precision components.

Filtered Cathodic Arc Sources: Magnetic filtering minimizes macroparticle (droplet) generation, yielding smoother surface finishes (Ra < 0.1 um).

Closed-Field Unbalanced Magnetron Configuration: Enhances substrate-zone plasma density, achieving film adhesion scratch-test critical load Lc >= 80 N.

Dual-Gas Flow Regulation: Closed-loop feedback control using capacitance manometers and high-precision MFCs for reactive gases (N2, C2H2, O2).

Modular Deposition Sources: Interchangeable planar and cylindrical layouts enable rapid target switching for multi-layer architectures.

Roughing Pump: Rotary vane or dry screw mechanical backing to eliminate oil backstreaming.

High Vacuum Pump: Magnetic levitation turbo molecular pump (>= 3200 L/s) paired with a roots blower.

Sealing & Valves: Pneumatic gate valves, ISO-F/CF flanges with Viton/metal gaskets; helium mass spectrometer leak rate < 1 x 10^-9 Pa*m^3/s.

Pressure Monitoring: Combined Pirani and cold cathode ionization gauges.

Standard Cathode Targets: Ti, Al, Cr, TiAl, Zr, Cu, Graphite (purity >= 99.95%).

Substrate Materials: Cemented carbides (WC-Co), HSS, alloy steels (SKD11, 40Cr), titanium alloys (Ti-6Al-4V), and stainless steel (304, 316L).

Pre-Treatment: Requires ultrasonic degreasing and in-situ argon plasma ion etching (Ar+ bombardment) to eliminate surface oxides prior to deposition.

Cutting & Forming Tools: End mills, hobbing cutters, and inserts coated with TiAlN/TiN to extend tool life by 200% - 400% under dry machining.

Automotive Components: Piston rings, injector pins, and tappets coated with CrN/DLC to reduce boundary friction and scuffing.

Medical Devices: Orthopedic screws, surgical blades, and dental abutments utilizing TiN/ZrN for biocompatibility and corrosion resistance.

Industrial Hardware: Mold cavities and precision gears requiring high surface hardness (> 3000 HV).

Chamber Sizing: Tailored inner diameters and height profiles scaled to specific batch volumes or oversized workpieces.

Cathode Layout: 4 to 12 configurable arc source slots positioned symmetrically to ensure thickness distribution within +/- 8%.

Bias Integration: Optional high-power pulsed magnetron sputtering (HPPMS) hybrid integration alongside standard cathodic arc sources.

Automation: Integration with automated loading arms and SCADA manufacturing execution systems.

Material Inspection: Spectrographic analysis verifying raw target metallic purity (>= 99.95%).

Structural Testing: CMM dimensional verification of chambers and hydrostatic pressure testing of cooling channels.

Factory Acceptance Testing (FAT): 72-hour continuous dry-run test covering mechanical rotation, pump-down curves, and thermal stability.

Coating Verification: Test coupons evaluated via pin-on-disk wear testing, Rockwell indentation, and cross-section FESEM thickness analysis.

Site Preparation: Detailed engineering documentation for floor load limits, cooling water flow rates, and electrical busbar requirements.

Commissioning: On-site installation, vacuum calibration, and baseline process recipe handover by field engineers.

Operator Training: Structured programs covering routine maintenance, target replacement, leak hunting, and basic PLC troubleshooting.

Lifecycle Support: Remote diagnostic interface integration for real-time parameter logging and rapid fault isolation.
