Corrosion Behavior of DLC Coating Alloyed by Titanium

Popis výsledku v původním jazyce

Properties of DLC (diamond-like carbon) layers provide for their broad use in medical applications. Their tribological properties are frequently utilized in big joint implants. Another benefit is offered by their barrier effect. In the frame of presentedwork the corrosion behavior of DLC-Ti alloyed coatings formed on TiNbTa alloy in environments to which dental implants may be exposed was studied. Electrochemical impedance spectroscopy, XPS and a cell colonization test were employed in the study. Influence of DLC alloying by titanium was tested on samples with 3 levels of titanium amount. According to results of XPS analysis, surface concentration of titanium was 3.4, 10.2 and 23.6 at.%. Unambiguous and marked peak of titanium carbide was detected only in the case of highest concentration of titanium. Corrosion resistance of TiNbTa/Ti/DLC and TiNbTa/Ti/DLC-Ti was in low-aggressive physiological solution slightly different nevertheless very high in both cases. Electrochemical behaviour
