Corrosion behavior and mechanism of selective laser melted Ti35Nb alloy produced using pre-alloyed and mixed powder in Hank’s solution

This work investigated the corrosion behavior and mechanism of selective laser melted (SLM) Ti35Nb separately using mixed powder (Ti35Nb-M) and pre-alloyed powder (Ti35Nb-P) in Hank’s solution. Both types of samples demonstrate similar corrosion behavior, and double-layered oxide films form on the TiNb regions in both Ti35Nb-M and Ti35Nb-P. However, Ti35Nb-P has more stable oxide films than Ti35Nb-M because the outer porous oxide layer formed on...
