Journal ArticleDOI
Development of a flexible nanocomposite TiO 2 film as a protective coating for bioapplications of superelastic NiTi alloys
Diego Pinheiro Aun,Manuel Houmard,Michel Mermoux,Laurence Latu-Romain,J.C. Joud,G. Berthomé,Vicente Tadeu Lopes Buono +6 more
TL;DR: An experimental procedure to coat superelastic NiTi alloys with flexible TiO 2 protective nanocomposite films using sol-gel technology was developed in this article to improve the metal biocompatibility without deteriorating its supecrelastic mechanical properties.
Journal ArticleDOI
Photo-Induced Hydrophilicity of TiO2 Films Deposited on Stainless Steel via Sol-Gel Technique
TL;DR: In this article, photo-induced hydrophilicity of TiO2 films on stainless steel substrates and silicon wafers using two different sol-gel routes has been investigated.
Journal ArticleDOI
Reduction of chromium volatilisation from stainless steel interconnector of solid oxide electrochemical devices by controlled preoxidation
Wichitra Wongpromrat,G. Berthomé,Valérie Parry,Somrerk Chandra-ambhorn,Walairat Chandra-ambhorn,C. Pascal,Alain Galerie,Yves Wouters +7 more
TL;DR: In this paper, the authors measured chromium volatilisation from AISI 441 at 800°C in O 2 ǫ + 5%H 2 O and showed that it depends on gas velocity.
Journal ArticleDOI
Water and oil wettability of hybrid organic–inorganic titanate–silicate thin films deposited via a sol–gel route
Manuel Houmard,Manuel Houmard,Daniela C.L. Vasconcelos,Wander L. Vasconcelos,G. Berthomé,J.C. Joud,Michel Langlet +6 more
TL;DR: Hybrid organic-inorganic titanate-silicate thin films were deposited on silicium wafer via a sol-gel route in this article, where they were formulated by mixing an inorganic titanium alkoxide solution with solutions of hybrid organic inorganic silicon alkoxides partially substituted with non-hydrolysable alkyl chains.
Journal ArticleDOI
Surface charges of oxides and wettability: Application to TiO2–SiO2 composite films
TL;DR: In this article, the surface rugosity and the disjoining pressure caused by surface charges are able to explain the stability of a prewetting film, which can withstand to vaporization in weakly under saturated atmosphere, having a protective action despite a carbon contamination brought by standard atmosphere.
