AB - Were produced TiO2 thin coatings prepared, on substrates pure
Titanium using a deposition by magnetron sputtering technique, the
percentage of oxygen was varied, to study the behavior in terms of
friction coefficient corrosive fluids such as those related to the human
body. Electrochemical Impedance Spectroscopy (EIS), wear tests with
a tribometer, were performed to obtain the tribo-corrosion mechanism
of deterioration, taking into account the dual corrosion wear system.
The phases were identified by X-ray Photoelectron Spectroscopy (XPS)
high resolution. It is determined through the tests performed that the
surface treatment has a different effect for each percentage of oxygen
influenced by the simulated body environments. The wear performance
analysis indicated that the TiO2 film's protection had increased as the
percentage of oxygen in the gas mixture (Ar/O2) varied and other
synthesis parameters such as deposition time, target power, and
substrate temperature remained constant.
