Liquid Phase Deposited TiO2 Films on Stainless Steel Mesh for Corrosion Resistance Application

Liquid phase deposition (LPD) method was used to prepare corrosion protective titanium dioxide (TiO2) film coatings on the stainless steel mesh which is composed of steel wires at a relatively low temperature (80°C). The as-prepared TiO2 coated samples were characterized using X-ray diffractometry (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectra (EDX). It was observed that the TiO2 film coatings could conformally coat the stainless steel wires which play a significant role in the corrosion resistance. The corrosion resistance of the samples was evaluated using Tafel polarization curves in a three-electrode electrochemical examination system. The TiO2 deposited samples all showed a certain improvement of corrosion resistance. Compared with the sample prepared in the acid condition (PH=3.7), the low alkaline (PH=9.5) sample could provide better corrosion protection which could increase the corrosion potential (Ecorr) from-0.53 V to-0.17 V.

Titania Films

Titanium dioxide thin films were deposited onto sola-lime glass substrates by reactive magnetron sputtering. Fine stainless steel mesh sheets with different aperture sizes were applied as masks over glass substrates to allow the deposition of the coatings with micro-patterned structures and, therefore, enhanced surface area. Non-patterned titania films were deposited for comparison purposes. The titanium dioxide films were post-deposition annealed at 873 K for crystallinity development and then extensively analysed by a number of analytical techniques, including scanning electron microscopy (SEM)/energy-dispersive X-ray spectroscopy (EDX), optical and stylus profilometry, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and UV-Vis spectroscopy. The photocatalytic activity of non-patterned and micro-patterned titania films was assessed under UV light irradiation by three different methods; namely methylene blue, stearic acid, and oleic acid degradation. The results revealed that the micro-patterned coatings significantly outperformed non-patterned titania in all types of photocatalytic tests, due to their higher values of surface area. Increasing the aperture of the stainless steel mesh resulted in lower photocatalytic activity and lower surface area values, compared to the coatings deposited through a smaller aperture mesh.
