Resumo
Titanium and its alloys are widely used in dental implant manufacturing due its favorable properties, such as, biocompatibility, high mechanical
strength and high corrosion resistance. This last one, is a result of the ability of titanium to form an oxide film (TiO2) in contact with oxygen.
However, a several factors can accelerate the corrosion process of implants in contact with the oral environment, such as, acidification of the medium,
differential aeration, inflammatory conditions, presence of protein and the junction of diferent metals. The goals of this research is to investigate the
corrosion effect of galvanic coupling between titanium alloy (grade V) and stainless steel 316L. The investigative technique adopted was the scanning
vibrating electrode technique (SVET) in phosphate buffer solution simulating inflammatory conditions. The results showed detrimental effects of acidity
of the environment, induced by inflammatory conditions, accelerate the oxidation of Ti-6Al-4V. SVET maps and SEM images for the junction of the
different metals showed that the region with the highest electrochemical activity it is at the interface between the metals, mostly concentrated on the
Ti-6Al-4V alloy, depending on the conditions of the medium.
