The DLC coating gives excellent protection against abrasion, tribo-oxidation and adhesion (scuffing). The coating permits surface pressures that, under normal conditions, would lead at once to scuffing and cold welding. This reduces friction losses to a minimum. The good corrosion resistance protects the substrate from destructive attack. The Rockwell hardness on the outside is double a Phosphate BCG.
