“…It indicates that the chemical status for the chromium is in oxidized state. The binding energy of the latter peak Cr-O bond is 577.6 eV and this fits the Cr(OH) 3 perfectly. There has been report that the bonding energy in Cr 2 O 3 is 576.8 eV and in CrO 2 is 576.3 eV.…”

“…It is difficult to ascertain the adscription of the peaks if referring to the different reported values listed in Table 1. However, with reference to the earlier Section on Results and Discussion on the deconvolution of Cr peaks, it is reasonable to conclude that the higher sub-peak at 531.2 eV in spectrum (a) is associated with Cr(OH) 3 and Cr 2 O 3 , which diminishes (or become undetectable because of limitation of machine sensitivity) from the spectrum inside the coating. The other peak centered at 530.3 eV is associated with SnO 2 /SnO 4 .…”

The chromate conversion coating formed on commercial tinplate via a cathode electrolytic dichromate treatment has been studied by X-ray photoelectron spectroscopy (XPS) and electrochemistry methods. Through the analysis of the XPS, it was shown that there existed Cr, O, and Sn in the chromate coating and the chromate film consisted mainly of Cr(OH) 3 , Cr 2 O 3 , Sn, and SnO x . The current density decreased with increasing of the electric charge. The corrosion resistance for tinplate is relative with the content of chromium in the passivation film.

“…Tinplate is a thin low-carbon mild steel sheet, cold reduced, coated on both sides with pure electrolytic tin, linking the strength and formability of the steel with the corrosion resistance and weldability of the tin 1,2 . Tinplate is largely used in food packaging, being ideally suited for this purpose since it is non-toxic, light in weight, strong, and corrosion-resistant 3 .…”

Effect of curing temperature and architectural (monolayer and bilayer) of hybrid films modified with polyethylene glycol for the corrosion protection on tinplate

et al. 2014

Hybrid films obtained by a sol-gel process are based on two important reactions: hydrolysis and condensation. The condensation reaction is influenced by the curing temperature, since it induces the development of the intrinsic properties of the gel. The aim of this work is to coat tinplate, a substrate widely used in the packaging industry, with monolayered and bilayered hybrid films modified with polyethylene glycol and obtained through dip-coating. The results showed that the bilayered hybrid film obtained at 60°C had a higher layer thickness, and the best performance in the electrochemical assays, as well as the most hydrophobic character, in relation to the other samples. For the monolayered systems, the 90°C-cured system showed a lower layer thickness; however, this system showed a more compact, uniform and less porous layer, and presented better electrochemical impedance results, in comparison with the 60°C-cured samples.

Corrosion Mechanism Suggested Based on Electrochemical Analysis and SVET for Uncoated Tinplate and Post Coated With a Hybrid Film

et al. 2017

The tinplate, used in the packaging sector and formed from a metal substrate, comprises a steel base which has undergone a surface treatment to produce a thin layer of FeSn 2 , a tin layer and an oxide tin layer. Currently, packaging using surface treatment is based on the use of chromates because these metals provide an excellent corrosion resistance. Nontoxic alternatives to pre-treatments have been developed in recent years to replace the chromate process. The aim of this work is to analyze the performance of a new hybrid organic-inorganic film obtained from sol-gel consisting of the alkoxide precursors 3-(Trimethoxysilylpropyl)methacrylate (TMSM) and tetraethoxysilane (TEOS) with the addition of cerium nitrate with the scanning vibrating electrode technique (SVET), and electrochemical and morphological characterizations. Moreover, the evolution of the corrosion of the substrate was evaluated to propose a mechanism of corrosion. The results showed a galvanic coupling between the Sn/SnO 2 coat (cathode) and the defects exposed at the ferrous base (anode). The organic-inorganic hybrid film containing a cathodic corrosion inhibitor was able to retard the corrosion of the tinplate.
