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: CrAlON 1.8 µm + a-C:H 50 nm
• Outcome: Tool life 4× longer, scrap −40 %

Case 3 – Medical Drill

• Client: US MedTech startup, 2024
• Challenge: 316L needs CE-compliant low-friction finish
• Stack: ta-C 300 nm + Cr 30 nm adhesion
• Outcome: Penetration force −25 %, CE mark granted

5. Global Standards & Sustainability

• ISO 9001:2015 / IATF 16949 / ISO 13485
• REACH, RoHS, FDA 21 CFR §175.300
• Energy: 0.45 kWh per m²
• Waste: Zero liquid effluent
