WebThe plasma is generated by a dc discharge in a cascaded arc in argon and/or hydrogen. The power to the plasma is typically 2–8 kW. The pressure in the plasma source is 200–700 mbar. The plasma expands supersonically into the deposition chamber, where the pressure is typically 0.1–0.3 mbar. WebDLC coatings can have different structures and properties that rely on the ratio of SP 3 (diamond) and SP 2 (carbon) or other fillers like hydrogen, silicon, and metal in the layer. IBC’s DLC coatings meet MIL-PRF-32711 specification for military firearms. Characteristics: High hardness Low coefficient of friction (0.02 – 0.15)
