PVD Coating Durability: The 2024 Endurance Blueprint for Extreme Environments
1. What PVD Coating Durability Really Means
| Metric | TiAlCrN | ta-C DLC | Electroplated Ni |
|---|---|---|---|
| Hardness (HV) | 2 900 | 3 000 | 700 |
| Wear Rate @ 600 °C (mm³/N·m) | 1.1×10⁻⁶ | 5.2×10⁻⁷ | 5.0×10⁻⁵ |
| Salt-Spray (h) | 1 200 | 1 000 | 48 |
| Thermal Cycle ΔT | 1 000 °C | 1 000 °C | 300 °C |
| REACH Status | ✅ Compliant | ✅ Compliant | ⚠️ Restricted |
2. 2024 Durability Matrix – Film vs Environment
| Film | Thickness (µm) | Max Temp (°C) | Salt-Spray (h) | Wear Rate | Typical Use |
|---|---|---|---|---|---|
| TiAlCrN | 1–5 | 1 000 | 1 200 | 1.1×10⁻⁶ | Turbine blades |
| CrN | 1–4 | 600 | 800 | 1.6×10⁻⁶ | EV motor punches |
| ta-C DLC | 0.1–3 | 1 000 | 1 000 | 5.2×10⁻⁷ | Medical drills |
| TiN | 0.5–3 | 500 | 500 | 2.0×10⁻⁵ | Cutting tools |
3. How Durability Is Measured – Lab to Field
| Test | Standard | KPI | Result |
|---|---|---|---|
| Pin-on-Disc Wear | ASTM G99 | Wear rate | 5.2×10⁻⁷ mm³/N·m (ta-C) |
| Salt-Spray Corrosion | ASTM B117 | Corrosion hours | 1 200 h (TiAlCrN) |
| Thermal Shock | MIL-STD-810 | 1 000 °C ↔ 25 °C | 100 cycles, 0 delamination |
| Scratch Adhesion | ISO 20502 | Scratch load | 110 N (CrN) |
4. Three 2024 Case Studies
Case 1 – Aerospace Turbine Blade
-
Client: European OEM, 2024
-
Challenge: 850 °C fretting at dovetail
-
Stack: TiAlCrN 2 µm + a-C:H 200 nm
-
Outcome: Wear scar < 5 µm after 1 000 h; maintenance interval doubled
Case 2 – EV Motor Lamination Die
-
Client: US EV Tier-1, 2024
-
Challenge: 0.35 mm electrical steel sticking at 400 °C
-
Stack: TiAlCrN 1.8 µm + a-C:H 50 nm
-
Outcome: Tool life 4× longer, scrap −40 %
Case 3 – Medical Drill (ta-C DLC)
-
Client: US MedTech startup, 2024
-
Challenge: 316L needs CE-compliant low-friction finish
-
Stack: ta-C 300 nm + Cr 30 nm
