Properties of Diamond-Like Coating (DLC) :
Amorphous and hydrogenated amorphous carbon films have high hardness, low friction, electrical insulation, chemical inertness, optical transparency, biological compatibility, ability to absorb photons selectively, smoothness, and resistance to wear. It is one of the best coating method for high speed machine. DLC coating has higher resistance to wear comparing with Chromium or Teflon coating. It allows rotary hook running without lubrication and have high durability.
