摘要：Uniform nanostructure coating of TiO2 was prepared on 316L stainless steel by sol-gel method using Tetra-n-Butyle Titanat (TBT) as alkoxide material. 316L specimens were coated with the mentioned sol by dip coating method. The influences of preparation condition, pH of sol on TiO2 nanostructure coating were investigated. Their structural properties were examined at various calcination temperatures. The effect of drying cycle and solvent bath on crack reduction and the influence of withdrawal speed on thickness of the film was evaluated. Choosing of alcohol as a drying atmosphere could hinder the cracks formation. 400°C was desirable temperature to obtain nanoparticles from anatase phase. At this temperature it was found that TiO2 films exhibited a uniform anatase structure with particle size of about 15 nm.
