AB - Studies of materials in biomedical applications have focused on the
generation of new biomaterials and the development of surface
modifications, mainly of metals. Amorphous silicon containing diamond
like carbon DLC-Si coating deposited on titanium substrate with the
purpose of studying its biofunctionality. The behavior against the
phenomenon of tribocorrosion of coatings DLC-Si deposited on titanium
was evaluated, through the plasma-assisted chemical vapor deposition
technique. The nanoindentation technique was used to determine the
coating mechanical properties. The DLC-Si coatings were structurally
analyzed through X-ray diffraction (XRD) and X-ray photoelectron
spectroscopy (XPS) techniques, the characteristic binding energy for the
signal C1s was obtained from XPS. Via XRD results the amorphous
structure of DLC-Si coating was determined. The triboelectrochemical
results indicate that the coating shows an adequate wear and to corrosion
protection when exposed to the synergic mechanism, thus demonstrating
the protective coating effect
