Abstract Scope |
The present research aims in investigation and analysis of spatial variation in electrochemical behavior of Ti6Al4V additively printed by laser powder bed fusion, also known as LPBF. Electrochemical behavior of the LPBF printed Ti6Al4V was evaluated by potentiodynamic polarization measurements and electrochemical impedance spectroscopy, at various regions along the build direction, in chloride containing medium. Varying electrochemical behavior was further characterized using scanning electron microscopy and X-ray diffraction which confirmed the variation in (002) texture in the build plane of LPBF printed Ti6Al4V. Also, a Multiphysics computational models developed by finite element method was used in understanding the thermokinetics of the LPBF printed Ti6Al4V and was also conducive in apprehending the spatial variation of electrochemical behavior. |
