In vitro corrosion behaviour of some titanium alloys designated to oral implantology

Abstract

The paper presents a study on the corrosion behavior of some biocompatible titanium alloys designated for the use in dental implantology field. The purpose of the study was to determine the corrosion behavior of three titanium alloys with original composition: Ti-36.5Nb-4.5Zr-3Ta-0.16O, Ti-31.7Nb-6.21Zr-1.4Fe-0.16O and Ti-20Nb-5Ta, in the following simulated physiological environments: artificial saliva and Hank's solution, using the linear polarization technique. In artificial saliva Ti-36.5Nb-4.5Zr-3Ta-0.16O alloy showed the best corrosion behavior, followed by Ti-20Nb-5Ta and Ti-31.7Nb-6.21Zr-1.4Fe-0.16O alloys. In Hank's solution, Ti-20Nb-5Ta alloy had the best corrosion resistance, followed by the other two alloys, with relatively close values.
