“…On the other hand, TiO 2 has been studied on different occasions, proving to be in the same way a material with good abrasive properties, from nanoparticles in additives [4,5] to thin films deposited on glass and titanium substrates [6,7]. The union of both components has been shown to achieve significant improvements in photocatalytic processes [8][9][10], photoelectrochemical processes [11], and electrical properties [12]. But given the scarcity of research involving a tribological and mechanical analysis, this work focused precisely on studying and improving the protective behavior of TiO 2 by incorporating carbon into its structure, using a two-step synthesis route:…”

With the use of the sputtering technique, carbon incorporation was carried out on TiO 2 anodized with HCl. FE-SEM study revealed the formation of tubes and/or fibers nanostructures on the surface of the acquired samples. It was possible to identify the presence of carbon by vibrational modes and EDS analysis. The nanoindentation test demonstrated how the carbonincorporated TiO 2 samples improved the nanohardness and elastic modulus compared to titanium and TiO 2 anodized. The presence of carbon was able to reinforce the bond of the TiO 2 layer with the substrate, which improved adhesion and abrasive behavior, and in turn, reduced the friction coefficient up to 89% compared to titanium.
