Distinction In Corrosion Resistance Of Selective Laser Melted Ti-6al-4v Alloy On Different Planes, Nianwei Dai, Laichang Zhang, Junxi Zhang, Xin Zhang, Qingzhao Ni, Yang Chen
Research outputs 2014 to 2021
Electrochemical measurements and microstructural analysis were performed to study the corrosion resistance of different planes of Ti-6Al-4V alloy manufactured by selective laser melting (SLM). The electrochemical results suggest that its XY-plane possesses a better corrosion resistance compared to XZ-plane in 1 M HCl solution, in spite of slight difference in 3.5 wt.% NaCl solution, suggesting that the different planes exhibit more pronounced distinction in corrosion resistance in harsher solution system. The inferior corrosion resistance of XZ-plane is attributed to the presence of more α′ martensite and less β-Ti phase in microstructure for XZ-plane than for XY-plane of the SLM-produced Ti-6Al-4V …
