? 2022Effect of scanning strategy (CB, R90, R67) on the microstructure and corrosion behaviors of Ti35Nb2Ta3Zr0.3O (wt%, TNTZO) prepared by selective laser melting (SLM) in 3.5 wt% NaCl solution were systematically investigated. The results of electrochemical tests indicated that the corrosion resistance of vertical planes was better than that of horizontal planes for all three scanning strategies, particularly sample R67 and R90, of which sample R67 performing the highest corrosion resistance. The dependence of corrosion resistance on the scanning strategy only exhibits for the vertical planes. The various electrochemical properties of horizontal and vertical planes are attributed to the density of crystallographic texture more than the grain boundary for the as-built TNTZO alloy.
