Structure and Specifications
The PVD-1213 series is a vacuum ion coating system specifically designed for protective and functional coatings on high-temperature alloys. It features a cylindrical chamber with an internal dimension of Φ1200 × 1300 mm (H) and an effective deposition area of 1000 × 1000 mm (H), capable of processing multiple medium- to large-sized components simultaneously. The chamber is equipped with a dual-layer circulating water-cooling system that maintains stable temperature during high-energy deposition, preventing overheating and stress imbalance in the coatings. This ensures long-term process stability and repeatability. The front-opening design allows easy loading, unloading, and maintenance, making the system ideal for advanced coating applications in aerospace, energy, and research sectors.
Arc Source and Process Configuration
The system is equipped with sixteen high-performance cathodic arc sources (Φ100 × 40 mm), each powered by a high-energy single-pulse DC arc power supply. This configuration achieves a high ionization rate and rapid deposition, producing coatings with excellent density, adhesion, and oxidation resistance.
System Configuration:
16 cathodic arc sources
16 single-pulse DC arc power supplies (200 A each)
1 bias power supply (HorTeng Truplasma 4020, 40 kW)
1 ion cleaning unit (AEGD)
The Arc Enhanced Glow Discharge (AEGD) ion cleaning system efficiently removes surface oxides and contaminants before deposition, improving coating adhesion and interfacial quality. The system supports multi-arc co-deposition and multilayer processes, allowing for the creation of composite, gradient, or multifunctional protective coatings as required.
Common Target Materials:
Typical target materials include high-temperature alloys such as NiCrAlY, MCrAlY, and other nickel- or cobalt-based alloys. These coatings provide excellent oxidation and corrosion resistance, ensuring reliable protection for components operating in extreme thermal environments.
Vacuum and Control System
The PVD-1213 is equipped with a high-performance vacuum system consisting of a turbomolecular pump and a mechanical backing pump, allowing rapid attainment of high vacuum and minimizing oxidation and impurity contamination. The fully automated control platform supports multi-channel parameter setting and real-time monitoring, enabling precise control over arc power, bias voltage, gas flow rate, and deposition time. The system also includes full data recording and traceability features, storing process curves and batch histories to facilitate quality control and process optimization.
Application Fields
The PVD-1213 is primarily used for high-temperature protective and oxidation-resistant coatings in aerospace, energy, and industrial applications where components must endure extreme temperature and corrosion conditions. Typical applications include:
High-Temperature Alloy Protection:
Coatings for nickel- and cobalt-based alloy components to enhance oxidation and corrosion resistance, extending service life.
Aerospace Engine and Gas Turbine Blades:
Protective coatings for turbine blades, combustor parts, and guide vanes to prevent oxidation, thermal fatigue, and degradation under high-temperature operation.
Industrial Gas Turbine Hot-End Components:
Coatings for critical hot-section parts such as nozzle rings and guide vanes, improving thermal stability and operational efficiency.
High-Temperature Corrosion-Resistant Layers:
Protective coatings for chemical processing equipment, heat exchangers, and high-temperature pipelines, preventing oxidation, sulfidation, and corrosion damage.
By combining multi-arc high-energy ion deposition with advanced ion cleaning technology, the PVD-1213 series produces dense, strongly adherent, and thermally stable coatings on high-temperature alloys. With outstanding process stability, reproducibility, and flexible control, it is an ideal high-end PVD coating system for aerospace engine, gas turbine, and energy equipment manufacturing industries.
