An Effect of Layer on Surface Morphology $TiO2$ Nanocoating Deposited on Mild Steel Surface

Titanium dioxide $(TiO2)$ Nanocoating is very useful materials and has wide applications especially in thin film applications [1]. Mild steel has tendency to corrode and lack of ductility but has an excellent of mechanical strength. Mild steel was used because of low cost and used as starting materials. $TiO2$ nanocoating was coated on low carbon mild steel surface with amount of carbon 0.16% to 0.19% [2]. The mild steel substrate coated $TiO2$ was prepared using sol‐gel spin coating technique [3], layer by layer deposition which speed (rpm) of spin‐coating and concentration of sol‐gel solutions were fixed. The surface topography and roughness of coating were investigated by atomic force microscopy (AFM) while phase and structure of the coating was investigated by X‐ray diffraction (XRD). The surface morphologies of coating were also measured through field emission scanning electron microscopy (FESEM). The suggested results were useful for coating of wall’s operation room. $TiO2$ Nanocoating is very useful coating protection and high potential demand due to high effectiveness of corrosion protection. This laboratory results can be expended to bigger scale coating process. It will contribute new technique and advance corrosion protection.
