摘要

The aim of this study was to develop a method to prepare WO_{<span style="font-family:Verdana;">3</span>}<span style="font-family:Verdana;">-TiO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> film which has high anticorrosion property when it was coated on type 304 stainless steel. A series of WO</span>_{<span style="font-family:Verdana;">3</span>}<span style="font-family:Verdana;">-modified TiO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> sols were synthesized by peroxo-sol gel method using TiCl</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> and Na</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">WO</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> as the starting materials. TiCl</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> was converted to Ti(OH)</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> gel. H</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">O</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> and Na</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">WO</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> were added in Ti(OH)</span>_{<span style="font-family:Verdana;">4</span>}<span style="font-family:Verdana;"> solution and heated at 95<span style="white-space:normal;">°</span>C. The WO</span>_{<span style="font-family:Verdana;">3</span>}<span style="font-family:Verdana;">-TiO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> sol was transparent, in neutral (pH~7) solution, stable suspension without surfactant, nano-c
