“…The use of the synthetic Al 2 O 3 with a grain size 250 μm after the surface modification by the sol-gel method, results in obtaining a tight ZrO 2 layer, which is a good barrier against the corrosive environment. Additionally, based on the obtained results and literature dates it can be concluded, that the pitting corrosion resistance increase with the deposited on the surface of the Ti-6Al-7Nb alloy the thin layer by the sol-gel method [5,7,11]. Moreover, regardless of type of the initial surface treatment, the micro-crack of the oxide layer was observed, which does not affect the quality of the obtained layers.…”

“…The musculoskeletal system insufficiency could cause injuries and lesion. Taking all these aspects into account, many scientists assess increase and summarize the knowledge of biomaterials, but also improve them and search for new solutions that guarantee optimal biotolernace in the tissue environment [1][2][3][4][5][6]. Currently, the vanadium-free Ti-6Al-7Nb alloy is one of the most popular and most prospective metal biomaterials used in medical and dental applications to made implants.…”

“…Included in the chemical composition aluminum can lead to nerve cell damage, allergy and osteomalacia, which is manifested as bone pain and frequently contributing to fractures. Additionally, the unstable passive surface layer and low tribological properties are limiting factors of the Ti-6Al-7Nb alloy usage in medical applications [5][6][7][8][9]. In order to eliminate unfavorable factors, it is necessary to use surface modification.…”
