Rare Metals, Volume 42, Issue 9, Page 3114-3129, September 2023., 2023 Graphic Abstract Abstract 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

Gongye shui chuli, 2014 使用电化学阻抗法及Tafel极化法在模拟低压工业锅炉炉水介质中研究了HEDP对20#碳钢的缓蚀性能，并探讨了炉水中Ca2+、Cl-以及Cl42-对HEDP缓蚀性能的影响。实验结果表明：在模拟炉水介质中，当HEDP投加量为25 mg/L时，其对碳钢具有最佳的缓蚀效果；HEDP对碳钢腐蚀的抑制主要作用于阳极失电子反应，HEDP是一种以抑制阳极为主的缓蚀剂；炉水中Ca2+的存在会影响HEDP对碳钢电极的极化过程；Cl-、Cl42-等侵蚀性阴离子会促进腐蚀的加剧，影响HEDP的缓蚀性能。
