The Tribological and Corrosion Properties of Anodized Ti6Al4V/316L Bimetallic Structures Manufactured by Additive Manufacturing

Abstract

In this study, layered Ti6Al4V/316L substrates were formed by Laser Powder Bed Fusion. TiO2 ceramic layers were produced on the Ti6Al4V/316L structures by an anodic oxidation method at different coating times (15, 30, and 60 min) to advance the wear features of layered Ti6Al4V/316L structure. The surface characterizations, wear and electrochemical behaviors of all specimens were examined via scanning electron microscopy, X-ray diffraction, a microhardness device, a reciprocating tribo-tester, and electrochemical corrosion experiments. According to the outcomes, the wear and corrosion resistance of the anodic oxidized specimens were higher compared to untreated 316L and layered Ti6Al4V/316L substrates, and the best results were obtained from the anodized specimen treated for 60 min.
