8. Cell and Bacteria-Baterial Interactions on the Ti10Mo8Nb Alloy After Surface Modification
The purpose of this study is the surface modification of Ti10Mo8Nb experimental alloy by using TiO2 nanostructure growth. Ingots of the Ti10Mo8Nb experimental alloy were produced by fusion from sheets of molybdenum, niobium, and titanium commercially pure in an arc melting furnace under argon atmosphere. The potentiostatic anodic oxidation was performed usin
