             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.",
