Nanoporous Oxide Surface Obtained on Titanium (Grade 5) Alloy to Analyze Surface Hardness and Anti-Wear Character



This research work exhibits a technique to enhance the surface character of nanoporous oxide layer obtained on Ti6Al4V by an anodic oxidation method and by critically analyzing its tribological behavior along with improved surface hardness. The effects of anodizing parameters like electrolytic concentration, anodic voltage, time, current density, etc. were monitored to attain well-ordered porous oxide film on the titanium substrate. Phase analysis and the morphological survey of the anodized surface were performed by an X-Ray diffractometer and scanning electron microscopy (SEM), respectively. Phase analysis revealed that porous structure appeared at 0.4 M of sulfuric acid (H2SO4) and anodic voltage at 20 V; the phase transformation from anatase to rutile occurred at 0.5 M of H2SO4. Wear tests performed on pin-on-disc–type tribometer showed accumulated oxide layer (titanium dioxide) significantly enhanced wear-resisting strength, especially abrasive wear. Comparison between the anodized and nontreated/nonanodized surface with SEM micrographs was performed to determine the response of oxide film after wear. This work determines a large range of applications for the treated surface, especially for biomaterial.
