Hydrogen-Free DLC Coating, Evolved

DLC coating is a film that possesses both the hardness of diamond and the lubricity of graphite.

It is particularly suitable for aluminium alloy machining due to its excellent wear resistance and antiadhesion properties, especially in cutting tools.

Hydrogen-free DLC films have high hardness and provide superior wear and heat resistance, which is why they have been widely used in cutting tools.

Generally, while hydrogen-free DLC excels in wear and heat resistance, it faces the challenge of being prone to peeling due to the significant hardness difference from the substrate.

Mitsubishi Materials has overcome this issue by adopting a newly developed thin hydrogen-free DLC film with improved adhesion, thereby achieving an excellent balance of wear resistance and strong adhesion.

 

Features

Three Key Features of Hydrogen-Free DLC Coating

  • Thin Coating Effective for Precision Machining

Ideal for machining high-precision components, delivering excellent component surface finishes.

  • High Hardness with Excellent Wear Resistance

Its high hardness provides superior wear resistance, resulting in extended tool life.

  • Outstanding Adhesion

Achieves superior adhesion, suppressing sudden dimensional discrepancies caused by film peeling or chipping.

It’s environmentally friendly because of the performance efficiency improvements and longer tool life.

The colours of DLC coatings can vary in appearance depending on the thickness of the film.
However, this is only visual and has no effect on quality or performance.
