Abstract (english)

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 chemical composition Ti10Cr-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 (physiological solution, saliva and sweet carbonated beverage) at two temperatures (37 C and 39 C) in the same time interval. Concentrations of eluted metal ions were determined by inductively coupled plasma spectroscopy. The surface of the samples was observed by a light microscope and Vickers hardness was measured as well. pH of corrosive media was measured before and after the elution. The obtained results showed dependence of eluted metal ions on temperature as well as on type of corrosive media.
