             abstract = "Diamond-like carbon (DLC) has been widely studied due to its 
                         mechanical properties such as low friction coefficient, high 
                         hardness, and high adherence on different substrate materials. The 
                         unique combination of chemical and mechanical properties of DLC 
                         films has opened the possibilities for the electrochemical 
                         applications of these film materials. In this chapter, a review of 
                         DLC films with extremally high hardness and very resistant to 
                         corrosion by incoporating crystalline diamond (CD) particles 
                         during the deposition process will be presented. These films were 
                         for the first time developed in our laboratories and the 
                         characterization performed will be also showed. The studies 
                         carried out in our laboratories show CD-DLC films improving DLC 
                         and stainless steel electrochemical corrosion resistance. CD-DLC 
                         prevented aggressive ions from attacking metallic surfaces, 
                         becoming a potential candidate for an anti-corrosion material in 
                         industrial applications, like pipelines in petroleum industry. It 
                         was also investigated the influence of the diamond particle sizes 
                         on the electrochemical corrosion resistance of these films. The 
                         electrochemical parameters obtained from the potentiodynamic 
                         polarization curves and the impedance were correlationated with 
                         the qualitative sp3/sp2 ratio of the CD-DLC films obtained from 
                         Raman scattering spectroscopy. The results show that both 
                         protection efficiency and impedance increase with the decrease of 
                         ID/IG ratio. It means the increase of sp3 bonds in DLC films 
                         reduce its electrochemical corrosion, improving the 
                         electrochemical protection efficiency and the impedance. In 
                         addition, diamond crystallites bigger than the DLC grain size 
                         reduced the pitting corrosion, which is an indication of the 
                         chemical inertness of the CD-DLC coatings to the Cl\− ions. 
                         The tribological behavior of these films under aggressive solution 
                         was also investigated. The presence of bigger CD particles 
                         increased the film roughness. In addition, these CD particles 
                         demonstrated to reduce DLC friction and wear. CD-DLC(500nm) films 
                         presented the lowest friction coefficient and wear rate under 5% 
                         NaCl saline solution. This result suggests the potential use of 
                         these films in aggressive environment even when suffer friction.",
