Energy storage ability and anti-corrosion protection properties of TiO2–SnO2 system / M.-J. Zhou in Materials and corrosion, Vol. 61 N° 4 (Avril 2010)  

Public ISBD [article]  inMaterials and corrosion > Vol. 61 N° 4 (Avril 2010) . - pp. 324–327 Titre : Energy storage ability and anti-corrosion protection properties of TiO2–SnO2 system Type de document : texte imprimé Auteurs : M.-J. Zhou, Auteur ; Z.-O. Zeng, Auteur ; L. Zhong, Auteur Année de publication : 2010 Article en page(s) : pp. 324–327 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : anti-corrosion protection  energy storage  photocathodic TiO2/SnO2  TiO2–SnO2 Résumé : TiO2/SnO2 and TiO2–SnO2 coatings were prepared on type 304 stainless steel by sol–gel method, respectively. TiO2/SnO2 coating is compared with TiO2–SnO2 coating in terms of energy storage ability and anti-corrosion property. The two coatings can be charged with reductive energy under UV irradiation in 3 wt% aqueous NaCl. The self-discharging time of the TiO2/SnO2 coating is slower than that of the TiO2–SnO2 coating. The slow discharging may be suitable for an anti-corrosion application for metal. In the case where TiO2/SnO2 coating electrode is electrochemically charged at −0.38 V (vs. SCE) for 1 h, it can maintain a good cathodic protection for type 304 stainless steel for 7 h in the dark, while the TiO2–SnO2 coating electrode can only maintain a good cathode protection for 0.5 h in the dark.

Photocathodic protection properties of NiP/TiO2 bilayer coatings by a combined electroless plating and sol–gel method / M.-J. Zhou in Materials and corrosion, Vol. 63 N° 8 (Août 2012)  

Public ISBD [article]  inMaterials and corrosion > Vol. 63 N° 8 (Août 2012) . - pp. 703–706 Titre : Photocathodic protection properties of NiP/TiO2 bilayer coatings by a combined electroless plating and sol–gel method Type de document : texte imprimé Auteurs : M.-J. Zhou, Auteur ; N. Zhang, Auteur ; Zhang, L., Auteur Année de publication : 2013 Article en page(s) : pp. 703–706 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Electroless plating  low carbon steel  NiP/TiO2 bilayer coating  photocathodic protection  sol–gel Résumé : A combined electroless plating and sol–gel method was developed for preparing a NiP/TiO2 bilayer coating to achieve an especial photocathodic protection effect for A3 low carbon steel. Photocathodic protection properties of the coating were investigated by the electrochemical method. Surface morphology and structure of the coating were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The results show that the open circuit potential (OCP) of the NiP/TiO2 coating electrode shifts to −0.42 V under UV irradiation, which is lower than the corrosion potential of A3 low carbon steel. When the light is turned off, the photocathodic protection effect cannot be maintained. In addition, the mechanism of photocathodic protection for the coating was also explored.
