DLC coatings: Where high hardness meets reduced friction
At voestalpine eifeler, our Diamond-Like Carbon (DLC) coatings offer advanced solutions to enhance tools and components performance, reduce friction, and increase durability in demanding industrial environments. With a unique structure combining carbon bonds, DLC coatings are ideal for high-wear, low-friction applications.
Technical Advantages of DLC Coatings
- High hardness: DLC coatings reach up to 3,000 HV, offering superior wear resistance.
- Low friction coefficient: DLC reduces friction to as low as 0.1 to 0.2, enhancing tool life and efficiency.
- Abrasion resistance: The smooth, dense structure resists surface degradation in high-speed cutting and forming.
- Reduced material adhesion: Prevents sticking of non-ferrous materials and plastics, ensuring smoother operations.
Performance in Industrial Applications
DLC coatings improve the lifespan and performance of cutting tools, forming tools, precision components, and plastic injection molds. They are especially effective in non-ferrous metalworking and dry running applications.
Biocompatibility and Versatility
DLC coatings are biocompatible, suitable for medical and food-grade applications, and can be combined with other PVD or CVD layers for enhanced performance.
Tailored Solutions for Harsh Conditions
We customize our DLC coatings to meet industry-specific needs, providing long-lasting protection and reducing operational costs in high-stress environments.
