  La aleación Ti6Al4V forma una capa de óxido en la superficie y es un material metálico empleado como biomaterial. La investigación determinó el nivel de desgaste y corrosión de la aleación fabricada por manufactura aditiva al igual que en la probeta de titanio elaborada por forja sometidas al anodizado. Se definió el uso del NaOH (0.1M) y H2SO4 (1M) como electrolitos, con un tiempo de 5 minutos, voltaje de 20 y 40V, pruebas de desgaste en Pinon Disk y resistencia a la corrosión en solución Hank. Evidenciándose la utilidad del anodizado en la superficie del titanio. El voltaje de 40V produce una capa de óxido uniforme con mayor espesor, disminuyendo el nivel de desgaste y la velocidad de corrosión. El electrolito adecuado es H2SO4ya que el NaOH produce más corrosión. La probeta fabricada por forja tiene mayor resistencia a la corrosión con respecto a la aleación fabricada por manufactura aditiva.

  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 H2SO4as NaOH produces more corrosion. Forging specimen has higher corrosion resistance than alloy made by additive manufacturing.
