Industrial PVD Coating Solutions: Ultra-Robust Surface Finishing from China’s JLY Precision Tech
1. What Are Industrial PVD Coating Solutions?
Industrial PVD coating solutions are vacuum-deposited nano-to-micron films engineered for extreme loads, temperatures and chemicals. Unlike decorative PVD, industrial variants focus on:
- Wear resistance ≥ 2 500 HV
- Thermal stability up to 1 000 °C
- Chemical inertness in sour gas, salt spray, blood plasma
- Dimensional fidelity – thickness tolerance ± 5 nm
Typical stacks include TiAlCrN, CrN, ta-C DLC, Al₂O₃/SiO₂ AR and Ag/Ni EMI films.
2. Technology Matrix – Which PVD Method for Which Industry?
| Method | Typical Stack | Thickness (µm) | Industrial Use Case |
|---|---|---|---|
| HiPIMS TiAlCrN | TiAlCrN gradient | 0.5–5 | Turbine blades, EV motor punches |
| Cathodic Arc CrN | CrN + a-C:H | 1–4 | Injection moulds, hydraulic rods |
| Filtered Arc ta-C | sp³-C | 0.1–2 | Medical drills, food slicer blades |
| Reactive Sputter Al₂O₃ | Al₂O₃/SiO₂ | 0.05–0.3 | Optical mirrors, sensor windows |
| Magnetron Ag/Ni | EMI multilayer | 0.05–1 | RF shields, 5G antennas |
