| description | •SLMed Ti6Al4V was tested in static/dynamic NaCl solutions with different concentrations.•The formed oxide film on SLMed Ti-6Al-4V includes TiO2, Ti2O3 and TiO.•The overall film thickness enhances with the increase in the Cl− concentration.•The film formed in dynamic conditions contains more defects.•The better corrosion resistance of the sample tested in static conditions was found.
In this work, the corrosion and passivation behavior of Ti-6Al-4V produced by laser powder bed fusion (L-PBF) were investigated in different concentration of NaCl solutions under static and dynamic conditions. Oxide films including TiO2, Ti2O3, TiO were formed on L-PBF-produced Ti-6Al-4V. The film thickness increased under both test conditions with increasing the Cl− concentration, and the film contained more TiO2 in dynamic conditions under the same Cl− concentration. The mechanism of the corrosion behavior and film growth under different Cl− concentration and electrolyte conditions were discussed by the relevant electrochemical and surface characteristic measurements, e.g. Mott-Schottky analysis, X-ray photoelectron spectroscopy. |
