In this study, TiO2 was coated on 316L stainless steel substrates via sol–gel/ dip coating method. The effects of surface roughness on the physical properties have been investigated. Scanning electron microscopy (FE-SEM), FTIR and X-ray diffraction (XRD) were used to investigate the morphological properties, identification of simple mixtures of organic and inorganic compounds and structure of crystal, respectively. Also, the effect of roughness on the hydrophobic property of coating measured by water contact angle. Water contact angle increased from 142.5∘ to 168.5∘ by increasing the roughness. From wettability results indicated that roughness had significant effect on the hydrophobic property of thin films.
