The versatility and affordability of additive manufacturing (AM) techniques has revolutionized metal manufacturing, processing, and prototyping. The corrosion behavior of additively manufactured titanium is subject to current research due to the lack of information on the influence of build parameters and the increasing popularity of AM. Five additively manufactured Ti-6Al-4V rectangular rod samples were built with varying scanning lengths. This variation changed proportions of (001) and (101) beta grains between samples, introduced lack of fusion defects, and created different sample porosity. Each sample was cut, mounted in epoxy, and tested with cyclic potentiodynamic polarization (CPP) scans to differentiate corrosion behavior. Pitting potential, primary open circuit potential, secondary open circuit potential, passive current density, and return beak potential results were extracted from CPP tests to compare each samples’ corrosion resistance. The purpose of this research is to determine how build parameters ultimately influence corrosion behavior.
