Advanced DLC Hard Coating Ion Plating System with Sputtering Technology
The SIMVACO Superhard Coating Ion Plating System represents the pinnacle of modern Physical Vapor Deposition (PVD) innovation, engineered to deposit ultra-hard, wear-resistant coatings—including Diamond-Like Carbon (DLC), nanocomposite films, and multi-layered architectures—onto precision tools, dies, and critical industrial components. Leveraging high-ionization plasma-enhanced Ion Plating (IP) within an ultra-high-vacuum environment (≤1×10⁻⁴ Pa), this system achieves unparalleled coating density (>98% theoretical density), atomic-level adhesion, and tailored functional performance. By integrating advanced process control and proprietary plasma source designs, the equipment transforms conventional tools into high-durability assets capable of withstanding extreme thermal, mechanical, and corrosive challenges in next-generation manufacturing.
Core Technical Innovations
1. Plasma-Enhanced Ion Plating (PEIP) Technology
- Process Mechanics: Combines arc evaporation (for high metal ionization rates) with pulsed bias voltage (up to -1,500 V) to accelerate ion bombardment, ensuring atomic-level intermixing at the coating-substrate interface for adhesion strength exceeding 100 N (ASTM C633).
- Multi-Arc & HIPIMS Hybrid Modes: Optional integration of High-Power Impulse Magnetron Sputtering (HIPIMS) enables deposition of ultra-dense nanocomposite coatings (e.g., TiAlSiN/DLC) with hardness values surpassing 45 GPa.
2. Adaptive Coating Architecture Design
- Gradient & Nanolayer Structures: Proprietary software supports programmable layer stacking (e.g., TiN-CrN-TiAlN-DLC) with individual layer thickness down to 5 nm, optimizing stress distribution and crack resistance.
- DLC Process Advancements: Hydrogen-free ta-C (tetrahedral amorphous carbon) coatings with sp³ bonding >70% achieve hardness of 2,500–8,000 HV, rivaling natural diamond.
3. Intelligent Process Control
- AI-Driven Parameter Optimization: Machine learning algorithms analyze historical data to auto-calibrate plasma density, bias voltage, and gas flow ratios for repeatable quality (±2% thickness tolerance).
- Real-Time Plasma Diagnostics: Integrated Langmuir probes and OES (Optical Emission Spectroscopy) monitor ion energy (1–50 eV) and species concentration, enabling closed-loop control of coating stoichiometry.
