Herein, the spatial variation in the electrochemical behavior of laser powder bed fusion (LPBF)‐fabricated Ti6Al4V alloy is investigated. The electrochemical behavior of LPBF‐printed Ti6Al4V is measured using potentiodynamic polarization and electrochemical impedance spectroscopy at different regions along the build direction. The varying kinetics in electrochemical response is characterized using scanning electron microscopy and X‐ray diffraction, which confirm the variation in (0002) texture in the build plane of LPBF‐printed Ti6Al4V. The thermokinetics of LPBF‐printed Ti6Al4V is understood by developing a multiphysics computational model using the finite‐element method, which is conducive to apprehending the spatial variation in electrochemical response kinetics.
