Influence of fluoride and/or bovine albumin and some common beverages on electrochemical properties of ionic liquid coated Zirconium for enhancing dental implantology performance

Myriads of materials have been used for dental replacement. The success of these materials relies on the ability to accommodate with the host oral cavity which provides an ideal and unique environment for study of biological processes involving metallic dental aids. Indeed, the essential acids and sugars in beverages have both acidogenic and cariogenic potential, resulting in dental corrosion. In this regard, a new approach for corrosion protection of Zirconium surface coated with 1-Butyl-3-methylimidazolium chloride ionic liquid ([Bmim]Cl) IL was investigated in artificial saliva containing fluoride and/or albumin, and some corrosive beverages. The morphology and composition of the ([Bmim]Cl) IL produced coat was characterized by means of scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM-EDX). The cyclic voltammetry and impedance spectra were recorded and the equivalent electric circuits were developed. The tafel slopes were noted from the linear polarization, and the corrosion parameters were calculated for bare and coated Zirconium. All results sustained the corrosion resistance enhancement for coated Zr, which ascribed to the beneficial effect of the adherent passive film caused by the thermal breakdown of IL molecules and the consequent adsorption of the Imidazolium molecule by planar configuration on Zr surface. Furthermore, computational chemistry modeling was used to understand the adsorption and corrosion inhibition performance for the IL on metal surface interface, and the results come in strong agreement with the experimental study.
