采用开路电位、动电位极化、电化学阻抗、恒电位极化、Mott-Schottky和X射线光电子能谱等测试技术研究了激光选区熔化增材制造Inconel 718合金(SLM Inconel 718)在0.1 mol/L NaOH溶液中的腐蚀行为，并与商用轧制Inconel 718合金(R Inconel 718)进行对比。结果表明，SLM Inconel 718合金与R Inconel 718合金均发生点蚀，SLM Inconel 718合金的点蚀优先发生在熔池边界和孔隙部位。相比R Inconel 718合金，SLM Inconel 718合金的活性更低、腐蚀速率更小、耐蚀性能更优，其主要原因在于：SLM Inconel 718合金表面生成的钝化膜中多孔NiO的含量更低，致密Cr2O3的含量更高，钝化膜更加致密，并且钝化膜的载流子密度更低，因此，SLM Inconel 718合金的钝化膜保护性能更好，耐蚀性能更优。

Inconel 718 alloy is a popular material used for additive manufacturing. Corrosion involvement is crucial for its application. The corrosion behaviors of the additive manufacturing Inconel 718 alloy in neutral NaCl solution and acidic solution have been thoroughly investigated and documented. However, information available in the literature regarding the corrosion behaviors of additive manufacturing Inconel 718 alloy in alkaline solution is insufficient. In this paper, the corrosion behavior of Inconel 718 alloy fabricated through selective laser melting (SLM Inconel 718) in NaOH solution was studied using open circuit potential (OCP), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), potentiostats polarization, Mott-Schottky analysis, and X-ray photoelectron spectroscopy (XPS). The results were compared with a commercial rolled Inconel 718 alloy (R Inconel 718). Pitting corrosion was observed in both SLM Inconel 718 alloy and R Inconel 718 alloy. SLM Inconel 718 alloy has lower activity and corrosion rate compared with R Inconel 718 alloy. Because the passive film formed on the surface of SLM Inconel 718 alloy has a lower content of porous NiO and a higher content of compact Cr2O3, the passive film is more compact; however, the donor/acceptor density is lower in the passive film.
