Title : Effect of electrophoretic deposition of zirconium oxide on the Ti13Nb13Zr titanium

Abstract:

Interest in biomedical engineering materials is still high. The number of diseases of the osteoarticular system is growing, and thus - it is necessary to fill tooth and bone defects in the face. For this reason, biomedical material for potential applications is constantly being sought. Titanium and its alloys have been used as implant materials since the second half of the 20th century. They are characterized by a low modulus of elasticity, very good mechanical properties and high corrosion resistance. Biomaterials made of titanium and its alloys are used as elements for the reconstruction of the oral and maxillofacial cavities as well as dental root implants. Many years of research have allowed the development of various techniques for modifying the surface of titanium and its alloys. However, the optimum surface for many applications has still not been achieved. The Ti13Nb13Zr titanium alloy has recently been used as a material for implants. It is slowly displacing the Ti6Al4V titanium alloy from the market. This is due to the presence of elements that negatively affect the human body. Research shows that aluminium and vanadium contained in the Ti6Al4V titanium alloy cause neurological disorders. On the other hand, niobium and zirconium contained in the Ti13Nb13Zr titanium alloy are elements inert to the human body. In addition - Ti13Nb13Zr has a lower modulus of elasticity than Ti6Al4V, thanks to which it is possible to come even closer to the Young's modulus of human bone. During this lecture, the results of the study of the surface of the titanium alloy Ti13Nb13Zr modified by electrophoretic deposition of zirconia will be presented. The electrophoretic deposition process was carried out at two different times and two different voltages. The surface characteristics were assessed by scanning electron microscope (SEM) and atomic force microscope (AFM). The chemical composition (EDS) was also assessed, and after the nanoindentation test, the hardness and Young's modulus of the modified surfaces were determined. A comparison of the reference and modified samples were also made, thanks to which the effect of electrophoretic deposition of zirconium oxide on the surface of the Ti13Nb13Zr titanium alloy was assessed.

Audience Take Away Notes:

• The results of the research on the modified surface of the Ti13Nb13Zr titanium alloy will allow for further development of research on this alloy as a material intended for implantology applications
• The lecture will provide information in which direction modifications of the surface of the Ti13Nb13Zr alloy and its evaluation can be further developed
• The speech can also be a means of self-development in the field of electrophoretic deposition of zirconium oxide on the surface of the Ti13Nb13Zr titanium alloy
