Tribocorrosion Behavior of Amorphous Carbon-Silicon Coated Titanium in Biological Medium
...
Bautista-Ruiz, Jorge | 2018
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
