Anodizing and its effects on mechanical properties and corrosion resistance of laser additive manufactured Ti-6Al-4V alloy

Ti-6Al-4V components were developed in different orientations (horizontal and vertical) using an additive manufacturing technique called direct metal laser sintering and heat treated under three different procedures. Anodizing (18- 22 V) the vertically built heat treated-2 specimen yields an optimum combination of mechanical properties and corrosion resistance tested in an acidic environment. The anodized (18- 22 V) heat treated-1 specimen built in horizontal orientation performed better in terms of combined mechanical properties and corrosion resistance tested in ringer solution.
