Sažetak
The superior mechanical properties of titanium alloys have singled out this type of alloy as an essential material for various applications, especially in the field of biomedicine. Due to the growing demand for permanent implants, it has become necessary to accelerate the growing development research of biomaterials, and thus titanium alloys. In this research, influence of corrosive media on elution of titanium-chromium- niobium alloy of new chemical composition, Ti- 10Cr-10Nb, was investigated. It was produced by melting and casting in an electric arc furnace in argon atmosphere. The alloy was tested in three different media (saline, saliva and sweet carbonated beverage) at two temperatures (37 ˚C and 39 ˚C), in the same time interval. The polished surface of the samples was observed by a light microscope and Vickers hardness was measured as well. Conductivity and pH of corrosive media were measured before and after the elution. Concentrations of eluted metal ions were determined by inductively coupled plasma spectroscopy. The obtained results showed dependence of chromium ions elution on temperature as well as on type of corrosive media.
