Lasers are multifunctional in material rapid processing and have a wide range of applications. Titanium dioxide (TiO2) is a very promising semiconductor due to various different properties, including optical, photocatalytic and antibacterial properties. It is generally known that laser processing can tailor surfaces with superior tribological, erosion resistant and antibacterial properties compared with untreated metal. At the same time, TiO2 exists in three basic polytypes: rutile, anatase and brookite. Therefore, the direct application of TiO2 is determined by the phase of TiO2 or their mixture for polycrystalline materials. Unfortunately, anatase and brookite are metastable phases and convert irreversibly to the rutile phase at a temperature ~600⁰C. This work proposes a possibility to control the phases of TiO2 layers using the laser-induced oxidation method of Ti foils. The metal was irradiated using a nanosecond fibre laser using a 1064 nm wavelength and 20 kHz repetition rate. The control of the formation of different TiO2 phases was achieved by changing the laser parameters such as intensity, dose, hatch spacing. The samples were characterised using an atomic force microscope (AFM), scanning electron microscope (SEM), etc. The phases of TiO2 formed by laser were determined at room temperature using Raman spectrometer Renishaw In-ViaV727 in backscattering geometry. The phonon excitation was performed by a green laser (Ar+, λ = 514.5 nm). The results of this study indicate that at higher intensities and dose TiO2 in the rutile phase was formed. The decrease of dose and intensities leads to the formation of a mixture of the phases with a small amount of anatase. The thickness of the TiO2 layer is proportional to the dose and inversely proportional to the hatch spacing.
