CELY-GONZALEZ, Angélica; PINEDA-TRIANA, Yaneth y GOMEZ-PUENTES, Oscar. Anodization of Ti6Al4V alloy manufactured by 3D printing and evaluation of corrosion and wear properties. Dyna rev.fac.nac.minas [online]. 2022, vol.89, n.224, pp.76-83. Epub 23-Mar-2023. ISSN 0012-7353. https://doi.org/10.15446/dyna.v89n224.101720.
Ti6Al4V alloy forms an oxide layer on the Surface and is metallic material used as a biomaterial. The investigation determined the level lof wear of corrosion of the alloy fabricated by additive manufacturing as in the titanium specimen made by forge subjected to anodizing. The use of NaOH (0.1M) and H2SO4 (1M) was defined as electrolytes, with a time of 5 minutes, a voltage of 20 and 40V, wear tests on Pin on Disk and corrosion resistance in Hank solution. Evidencing the usefulness of anodizing on the surface of titanium. The voltage of the 40V produces a uniform oxide layer with greater thickness, decreasing the level of wear and corrosion rate. The right electrolyte is H2SO4 as NaOH produces more corrosion. Forging specimen has higher corrosion resistance than alloy made by additive manufacturing.
