Two commercial studs, of gold-coated stainless steel and copper-zinc alloy, respectively, and a laboratory-made titanium stud were chosen for corrosion studies. Corrosion behaviour in a culture medium (CM) was studied using electrochemical impedance spectroscopy and polarization measurements, as a function of immersion time. The elements that leached out into the CM electrolyte were analysed by instrumental neutron activation analysis. Scanning electron microscopy and energy dispersive X-ray techniques were utilized in the analysis of the stud surfaces before and after their immersion in a CM solution. The cytotoxicity of the tested studs was also determined. The titanium stud showed the best combination of properties, high corrosion resistance and low cytotoxicity, while the gold-coated stainless steel stud occupied an intermediate position.
