abstract = "t Diamond-like carbon (DLC) films have been extensively applied as
a solid lubricant and as a protective coating due to their
attractive chemical, mechanical, and tribological properties.
Furthermore, these properties of DLC coatings can be improved with
the incorporation of nanoparticles of different materials,
especially diamond nanoparticles (DNPs). Herein, the incorporation
of chemical vapor deposition (CVD) DNPs was done from a deionized
aqueous colloidal solution by using a controlled pulsed valve,
which is an innovative aspect of this work. The CVD DNPs were
pulverized into the plasma region and incorporated in the DLC
films bulk with controllable size particle distribution and
density. In addition, an enhanced process to obtain DNPs with
suitable size distribution was established by using a high energy
ball milling technique, centrifugation, and a special chemical
cleaning process. The DLC films were deposited on a metallic
substrate via a modified, pulsed DC plasma-enhanced chemical vapor
deposition (PECVD) technique, with an additional cathode. X-ray
diffractometry (XRD) and scanning electronic microscopy (SEM)
techniques showed that an aqueous colloidal solution of
high-purity DNPs with a mean diameter of 32 nm was obtained.
Dynamic light scattering (DLS) results showed that it is possible
to control particle size distribution by varying the milling and
centrifugation time lengths. Therefore, a valuable result was that
DLC films could be deposited with DNPs by using clean water
without affecting deposition rate, the adhesion between the DLC
films and substrates, the structural quality of the film, and
keeping lower coefficient of friction.",
