Diamond-like carbon (DLC) coatings have attracted widespread attention in the last two decades, due to their desirable mechanical, optical, electrical, chemical and tribological properties. In recent years, the importance of improving the durability against cracking failure and reducing the friction between sliding and rotating surfaces. In this study, non-hydrogenated DLC coatings containing isolated nano-size carbon particles will be designed and fabricated by a novel PVD coating technology, i.e., closed field unbalanced magnetron sputtering ion plating. The in-situ incorporation of isolated nanoparticles into the DLC matrix with controlled size and dispersion can be realized by quenching plasma glow with short pulses of inert gas during DLC deposition. The embedded carbon nanoparticles inside the coatings will act as crack arrest elements. After deposition, the novel DLC coatings will be characterized and assessed comprehensively in terms of their hardness, fracture toughness, adhesion, residual stress, friction and wear. Dependences of the coating structure on the deposition parameters will be revealed systematically.
