Multi-Arc Ion Deposition Equipment

The Industrial Multi-Arc Ion Deposition System generates dense, high-adhesion thin films through high-current, low-voltage cathodic arc evaporation. Solid target materials (cathodes) are vaporized in a reactive gas atmosphere (such as N2, O2, or C2H2) to synthesize stoichiometric compound coatings. Engineered for high ionization rates exceeding 80%, this equipment yields exceptional film-to-substrate bonding strength suited for extreme mechanical load environments.

Magnetic Filtered Arc Technology: Integrated magnetic coils deflect macro-particles and droplets away from the substrate stream, producing ultra-smooth droplet-free surfaces for precision optics and cutting tools.

Closed-Loop Gas Flow Control: MKS mass flow controllers regulate reactive gas partial pressure within +/- 0.1 sccm stability thresholds during reactive deposition phases.

Substrate Temperature Management: Programmable radiant heater banks combined with backside argon gas cooling maintain substrate thermal budgets between 150C and 600C.

Automated Process Recipes: PLC-based control architecture executing multi-step deposition protocols from ion cleaning, gradient interlayer etching, to terminal functional coating.

Roughing Pump: Roots blower and rotary vane mechanical pump combination (Leybold / Edwards baseline).

High Vacuum Pump: High-throughput diffusion pumps or magnetically suspended turbomolecular pumps (>= 3200 L/s).

Valuation & Piping: Pneumatic stainless-steel vacuum gate valves, pneumatic angle valves, and elastomer-sealed KF/ISO flanges leak-tested via helium mass spectrometry (<= 1.0 x 10^-9 Pa*m^3/s).

Pressure Monitoring: Combined Pirani and Cold Cathode ionization gauges providing real-time feedback across atmosphere to ultra-high vacuum ranges.

Target Materials: Titanium (Ti), Chromium (Cr), Aluminum-Titanium (AlTi), Zirconium (Zr), Copper (Cu), Stainless Steel, and custom alloy targets (purity >= 99.95%).

Substrate Materials:

• Cemented Carbides (WC-Co)
• High-Speed Steels (HSS)
• Alloy Steels (SKD11, 316L, 4140)
• Titanium Alloys (Ti-6Al-4V)
• Engineering Ceramics and Heat-Resistant Superalloys

Cutting & Forming Tools: Deposition of TiAlN, AlCrN, and TiCN coatings on end mills, inserts, hobs, and stamping dies to increase surface hardness to 3200 HV and resist abrasive wear.

Automotive Components: Hard carbon (DLC) and CrN deposition on piston rings, fuel injection pins, and camshafts to reduce friction coefficients below 0.1 under dry running conditions.

Medical Implants: TiN and ZrN biocompatible diffusion coatings on cobalt-chromium and titanium knee and hip joints, minimizing metal ion leaching and wear debris generation.

Aerospace Hardware: Oxidation-resistant barrier coatings for turbine blades and fastener assemblies operating at elevated thermal thresholds.

Chamber Geometry: Vertical pit-type, horizontal front-loading, or double-door pass-through configurations tailored to existing shop-floor layouts.

Source Integration: Hybrid configurations merging cathodic arc sources with unbalanced magnetron sputtering (Ums) cathodes within a single chamber.

Jigging & Fixtures: Dedicated planetary or double-rotation tooling fixtures engineered via CAD/FEM simulation for specific component geometries (e.g., long extrusion dies or complex surgical screws).

Quality Management Standards: Designed, fabricated, and tested under ISO 9001:2015 quality management and ISO 14001 environmental management systems.

Aerospace & Medical Traceability: Process controls and documentation protocols fully aligned with NADCAP AC7102 (Heat Treating/Surface Enhancement) requirements upon request.

Leak Integrity: Every vacuum vessel undergoes helium mass spectrometer leak testing prior to assembly sign-off.

Electrical Safety: High-voltage insulation resistance testing and grounding continuity checks conforming to CE / IEC standards.

Run-off Testing: 72-hour continuous dry-run endurance testing of mechanical rotation drives, water-cooling flow switches, and PLC interlock systems.

Documentation Deliverables: Material mill test certificates (MTC), vacuum leak test certificates, electrical schematic packages, and NIST-traceable sensor calibration reports.

Site Preparation Guidelines: Comprehensive utility layout documentation covering cooling water flow rates (>= 30 m^3/h), ambient temperature ranges, exhaust ventilation, and electrical power drops (3-phase, 380V/480V, 50/60Hz).

Commissioning Services: On-site mechanical positioning, vacuum piping integration, electrical hookup, and baseline recipe optimization executed by resident senior field service engineers.

Operator Training: 5-day intensive on-site training addressing routine maintenance, vacuum troubleshooting, target replacement protocols, and parameter tuning for specific film structures.

Spare Parts Inventory: Critical wear components (cathode insulators, dark space shields, dynamic seals, and filament arrays) stocked regionally for dispatch within 48 hours.
