DLC Coating
DLC Coating stands for diamond-like carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance. DLC coatings can have different structures and properties that rely on the ratio of SP3 (diamond) and SP2 (carbon) or other fillers like hydrogen, silicon, and metal in the layer.
