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

Abstract:

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 (E_corr) from-0.53 V to-0.17 V.
