| 1 | Corrosion protection of AZ91D magnesium alloy by a cerium-molybdenum coating-The effect of citric acid as an additive显示文摘In order to improve the corrosion resistance of AZ91D magnesium alloy,a coating was formed by a potentiostatic technique from a solutions containing Ce(NO_(3))_(3),Na_(2)MoO_(4)and citric acid(H_(3)Cit).The degree of corrosion protection achieved was evaluated in simulated physiological solution by monitoring the open circuit potential,polarization techniques and electrochemical impedance spectroscopy(EIS).Surface analysis techniques(SEM,EDS,X-ray diffraction and X-ray photoelectron spectroscopy(XPS))were used for coating characterization.The film is mainly composed by cerium and molybdenum oxides and magnesium oxides and hydroxides.The obtained results show that the corrosion resistance of the coated electrodes has been increased significantly.This improvement in the anticorrosive performance is in part due to the corrosion inhibition properties of H_(3)Cit. | I.L.Lehr S.B.Saidman | 2018 | Journal of Magnesium and Alloys2018，6，4： | 11 |
| 2 | Formation of a cerium conversion coating on magnesium alloy using ascorbic acid as additive.Characterisation and anticorrosive properties of the formed films显示文摘Cerium-based conversion coatings were formed on AZ91D magnesium alloy by immersion of the substrate in solutions containing Ce(NO_(3))_(3),H_(2)O_(2) and ascorbic acid(HAsc).The characterisation of the films was performed by electrochemical and surface analysis techniques such as SEM,EDS,X-ray diffraction and X-ray photoelectron spectroscopy(XPS).The degree of corrosion protection achieved was evaluated in simulated physiological solution by the open circuit potential monitoring,polarisation techniques and electrochemical impedance spectroscopy(EIS).The presence of HAsc in the conversion solution causes changes in the morphology,adherence and anticorrosive performance of the films.The improvement in the corrosion resistance is closely associated with the corrosion inhibition properties of HAsc. | A.P.Loperena I.L.Lehr S.B.Saidman | 2016 | Journal of Magnesium and Alloys2016，4，4： | 7 |
| 3 | Improvement in the corrosion protection and bactericidal properties of AZ91D magnesium alloy coated with a microstructured polypyrrole film显示文摘In this work hollow rectangular microtubes of polypyrrole(PPy)films were potentiostatically electrodeposited on magnesium alloy AZ91D in salicylate solution.The substrate was previously anodized under potentiostatic conditions in a molybdate solution in order to improve the adherence of polymer.Finally the duplex film was modified by the incorporation of silver species.The obtained coatings were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and X-ray photoelectron spectroscopies(XPS)and the antimicrobial activity against the bacteria Escherichia coli was evaluated.The corrosion protection properties of the coatings were examined in Ringer solution by monitoring the open circuit potential,polarization techniques and electrochemical spectroscopy(EIS).The duplex coating presents an improved anticorrosive performance with respect to the PPy film.The best results concerning corrosion protection and antibacterial activity were obtained for the silver-modified composite coating. | A.D.Forero López I.L.Lehr L.I.Brugnoni S.B.Saidman | 2018 | Journal of Magnesium and Alloys2018，6，1： | 7 |
| 4 | 缓蚀离子存在条件下阳极氧化提高Ti-6Al-4V合金的耐蚀性显示文摘通过恒电流阳极氧化在Ti−6Al−4V合金表面制备彩色氧化物薄膜。采用3种不同的含有腐蚀无机缓蚀剂的水溶液(Na_(2)MoO_(4),NaH_(2)PO_(4)和NH_(4)VO_(3))进行阳极化处理,研究缓蚀剂阴离子对合金在Ringer溶液中腐蚀行为的影响。采用开路电位(OCP)、Tafel极化、线性扫描伏安(LSV)和计时电流(CA)等手段,评估处理后电极的腐蚀性能。通过释放的Mo、V和P,采用ICP-AES技术检测缓蚀剂离子的掺入。利用扫描电子显微镜(SEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)对形成的氧化物进行表征。结果表明,无论采用何种溶液,均获得无孔或裂纹的致密无定形氧化物。在Na_(2)MoO_(4)溶液中阳极氧化样品的腐蚀电流密度最低(0.11μA/cm^(2)),即使在Ringer溶液中浸泡168 h,仍能保护合金,而未检测到裂纹或腐蚀产物。XPS分析结果显示,钼以Mo^(6+)和Mo^(4+)的形式掺入氧化膜中。 | A.L.MARTINEZ D.O.FLAMINI S.B.SAIDMAN | 2022 | Transactions of Nonferrous Metals Society of China2022，32，6： | 2 |
