%X The aim of this study was to develop a method to
prepare WO3-TiO2 film which has high anticorrosion
property when it was coated on type 304 stainless steel. A series of WO3-modified
TiO2 sols were synthesized by peroxo-sol gel method using TiCl4 and Na2WO4 as the starting materials. TiCl4 was converted to Ti(OH)4 gel. H2O2 and Na2WO4 were added in Ti(OH)4 solution and heated at 95กใC. The WO3-TiO2 sol was transparent, in neutral (pH~7) solution, stable suspension without
surfactant, nano-crystallite and no annealing is needed after coating, and very
stable for 2 years in stock. WO3-TiO2 sol was formed with
anatase crystalline structure. These sols were characterized by XRD, TEM, and
XPS. The sol was used to coat on stainless steel 304 by dip-coating. The
