Study on corrosion resistance of galvanised steel passivated by a silanised cerium-tannic acid solution
In this study, a silanised cerium-tannic acid (Ce-TA) passivation solution was developed, and the effects of solution composition and passivation time on the corrosion resistance of galvanised steel were investigated. SEM-EDS, AFM, FTIR, and Raman spectroscopy were used to characterise the silanised Ce-TA-passivated samples. When the concentrations of both cerium nitrate and tannic acid in the passivation solution were 1.5 g/L, and the passivation duration was 45 s, the surface integrity and composition homogeneity of the passivated sample were good. Electrochemical measurements revealed that the |Z|0.01Hz and Rt values of the silanised Ce-TA-passivated samples first increased and then decreased with increasing passivation time. These values also first increased and then decreased with the increase in the amount of Ce-TA. The corrosion resistance efficiencies of the passivated samples exceeded 97 %. The corrosion resistance mechanism of silanised Ce-TA passivation is also discussed.
期刊介绍：
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
