Fabrication of titania coatings on stainless steel via laser-induced deposition of colloidal titanium oxide from sol-gel suspension

► TiO2 coatings were deposited on stainless steel via sol-gel and laser techniques. ► The deposition was realised using a fibre laser to irradiate over titania sol. ► The amount and phase structure of deposited coatings depend on laser conditions. ► Coatings crystallised in rutile and anatase were obtained at higher laser energy.
