Influence of CO2 exposure on pH value, electrochemical properties, and the formation of calcium-phosphate on Ti–6Al–4V under adjusted in vitro conditions in DMEM

Structure and properties of titanium and the Ti-6Al-7Nb alloy after isothermal oxidation

“…Usually, all types of grafts (metal implants) are made of the following materials: austenitic steels, cobalt alloys and titanium alloys [6][7][8][9][10][11]. Among metallic materials, titanium and its alloys are characterised by the best biocompatibility [7,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. However, pure titanium has poor mechanical properties, whereas titanium alloys frequently include in their chemical composition elements even from the carcinogenic group, such as for example the most popular titanium alloy: Ti-6Al-4V [2,8,[13][14][15].…”

Self-healing property of hydroxyapatite and octacalcium phosphate coatings on pure magnesium and magnesium alloy

“…The results reveal that HEPES was insufficient for buffering the medium against pH increase caused by Mg corrosion. In the future, it may be better to conduct immersion tests in a 5% CO 2 environment, because Höhn et al and Hofstetter et al suggested that immersion tests in cellculture media or simulated body fluids should be conducted under 5% CO 2 to buffer the solution, as in the body [42,43].…”

“…Magnesium and its alloys are suitable for use as orthopaedic implant materials because they are bioabsorbable/biodegradable and therefore do not require surgical removal. They also have high specific strength and low Young's modulus (41)(42)(43)(44)(45) GPa) similar to that of bone (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) [1][2][3][4][5].…”
