Abstract

In this work, electrochemical process was presented to polymerized eugenol on Gr.2 and Gr.5 titanium alloys before and after treated by Micro Arc Oxidation (MAO), where Gr.2 is commercial pure titanium and Gr.5 is Ti-6Al-4V dental alloys. The deposited layers were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The adhesion strength of polymeric thin-film was estimation by using pull-off adhesion test and the result was the adhesion strength of PE was (1.23 MPa) on Gr.2 before MAO and increase to (1.98 MPa) on Gr.2 after MAO treatment. The corrosion behavior of Gr.2 and Gr.5 alloy in artificial saliva environment at temperature ranged 293-323K has been studied and assessed by means of electrochemical technique spotentiodynamic polarization curves. The corrosion protection increased to 63% and 80% after coated blank Gr.2 and Gr.5 by PE, while when deposition PE on treated Gr.2 and Gr.5 by MAO, the protection efficiency (I%) increase to 68% and 81% respectively at 323K. The antimicrobial activities of the samples were evaluated against different bacteria and oral fungi (Candia), PE coating show antibacterial activity (28 and 25 mm) against S. aureus and B. Subtilis respectively and show antifungal activity (29 and 24 mm) against C. albicans and C. glabrata oral fungi respectively.
