DLC Surface Treatment for Coating Dies
- Wear resistance. The coating can reach a Vickers hardness of HV 2000–2300.
- Lubricity. A friction coefficient of 0.06–0.10 helps prevent adhesive wear.
- Coating thickness. The coating is 1–10 µm thick per side, with tight control of thickness variation. Thickness can be adjusted to suit the size of the die.
- Corrosion resistance. The DLC coating offers high resistance to corrosion.
