Structure and Specifications
This series of equipment is specifically designed for surface strengthening of cutting tools, molds, and wear-resistant components. It is mainly used for the mass production of hard coatings with high hardness and strong adhesion. The system adopts a vertical top-opening structure for easy loading and unloading, with simplified maintenance and convenient operation. The vacuum chamber diameter ranges from Φ800 to Φ1300 mm, with a height between 800 and 1500 mm, making it a medium-sized system adaptable to various workpiece sizes such as cutting tools, dies, punches, and precision parts. The overall structure is robust, with an efficient cooling system that ensures temperature stability and process consistency during long-duration coating operations.
Arc Source and Process Configuration
The system employs a multi-arc source design, with each cathodic arc source measuring Φ100 × 40 mm. The number of arc sources can be configured according to chamber size and production capacity requirements. Multiple arc sources can operate simultaneously or sequentially to achieve high-efficiency deposition and large-area uniform coating. The high-energy ion flux generated by the arcs forms dense, well-adhered coatings on the workpiece surface, significantly improving hardness, wear resistance, and oxidation performance. By adjusting arc current, substrate bias voltage, and gas composition, users can flexibly tailor coating composition and microstructure to meet different process requirements.
Vacuum and Control System
The system is equipped with a high-performance vacuum unit comprising a molecular pump and mechanical fore pump, capable of rapidly achieving and maintaining a high-vacuum environment. This ensures process purity and high film density during deposition. The fully automatic control platform allows precise setting of key parameters such as arc power, bias voltage, gas flow, and deposition duration, with real-time process monitoring. The system supports data logging, process traceability, and multi-recipe storage, making it ideal for continuous batch production and process optimization.
Performance Parameters
Coating hardness: ≥ 3000 HV (Vickers)
Film thickness: 2–5 μm (adjustable)
Excellent adhesion and superior wear resistance
Dense microstructure with strong oxidation resistance at high temperature
Depositable Materials
The system supports a variety of hard coating materials, including titanium nitride (TiN), chromium nitride (CrN), titanium carbonitride (TiCN), and aluminum titanium nitride (AlTiN). These coatings maintain stable performance under high temperature and high friction conditions, significantly improving surface wear life and corrosion resistance of the workpieces.
Typical Applications
This equipment is widely used in industrial fields requiring high hardness and wear resistance:
Cutting Tools: Turning tools, milling cutters, drills, taps, and forming tools—enhancing cutting efficiency, reducing tool wear, and extending service life.
Molds: Stamping, extrusion, die casting, and injection molds—improving surface wear resistance and anti-sticking properties.
Precision Components: Shafts, gears, piston rings, and valve cores—providing protective coatings that enhance wear and corrosion resistance.
The medium-sized hard coating ion plating system offers high deposition rates, dense microstructure, and excellent reproducibility. It reliably produces high-quality hard coatings such as TiN, CrN, and TiCN. With its stable performance, user-friendly operation, and low maintenance requirements, this system is ideal for industrial-scale mass production and process R&D, providing an efficient solution for improving the wear resistance and service life of manufactured products.
