oai:localhost:PNK-88272023-08-18T02:05:48Z Corrosion and passive film characteristics of 3D-printed NiTi shape memory alloys in artificial saliva Liu, Ming Zhu, Jia-Ning Popovich, V. A. L-PBF L-PBF NiTi alloy CC-BY Electrochemical tests and surface analysis were applied to study the corrosion behavior and passive film characteristics of three-dimensional-printed NiTi shape memory alloys fabricated by laser-powder bed fusion (L-PBF) in artificial saliva at 37 °C. The passivity of L-PBF NiTi shows to be influenced by the process parameters and resulting morphological and physicochemical surface properties. The results show that the defects at the surface of L-PBF NiTi can promote the passivation rate in the early stages of exposure but a slowly formed passive film shows the best corrosion protection. The thickness of the passive film is positively correlated with its corrosion protective performance. The L-PBF NiTi alloy prepared at a linear energy density of 0.2 J·m−1 and volumetric energy density of 56 J·mm−3 shows the least defects and best corrosion protection. An outer Ti-rich and inner Ni-rich dense passive film could be also obtained showing higher corrosion resistance. 2023-08-18T02:05:48Z 2023-08-18T02:05:48Z 2023 Book https://link.springer.com/article/10.1007/s12598-023-02329-6 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8827 en application/pdf Springer |
