Titanium passivated lacquered Tinplate cans in contact with foods
Corrosion Engineering Science and Technology, 2005Co-Authors: E. Almeida, N. Mora, J. M. Puente, M. R. Costa, N Cristofaro, Ramón Catalá, J. M. BastidasAbstract:This paper presents laboratory results of titanium passivated and chromium passivated Tinplate specimens lacquered in industrial lines. The lacquered materials were characterised and evaluated in terms of the chemical characteristics of the lacquer; its degree of curing; adhesion; porosity; corrosion resistance in synthetic food media; atmospheric corrosion susceptibility; and sulphur staining tendencies. Electrochemical impedance spectroscopy experiments were performed to assess corrosion protection capacity. Food cans manufactured from the lacquered materials were packed with sardines in olive oil and with tomato paste and shelf life tests were performed for up to 6 months, studying the inside of the cans by SEM and EDX techniques. Titanium passivated Tinplate seems to be an acceptable alternative to conventional chromium passivated Tinplate for food can applications.

Titanium-Passivated Tinplate for Canning Foods:
Food Science and Technology International, 2005Co-Authors: Ramón Catalá, J. M. Puente, J. M. Bastidas, E. Almeida, M. Alonso, Rafael Gavara, N. De CristaforoAbstract:Chromium-based treatments are currently used for the passivation of Tinplate, which produces a protective surface layer consisting of a mixture of metal chromium and chromium oxide. This passivation film is effective against the formation of tin oxides and corrosion by food media, and offers a good substrate for the adhesion of protective organic coatings. However, there is an increasing concern about environmental and health risks with this passivation treatment. The aim of this paper was to study a new environmental friendly passivation treatment based on a titanium compound, applied on Tinplate and afterwards lacquered with a conventional epoxyphenolic lacquer used for food can applications. The mechanical and electrochemical characteristics of the lacquered material and the metallic dissolution in canned sardines in tomato juice and peeled tomato were similar to those obtained with conventional Cr-passivated Tinplate. According to these results titanium treatment could be considered an alternative to ...

Environmentally friendly coatings for Tinplate cans in contact with synthetic food media
JCT Research, 2004Co-Authors: E. Almeida, N. Mora, J. M. Bastidas, M. R. Costa, N Cristofaro, J. M. PuenteAbstract:This article presents the materials, methods, and main results obtained in an experimental study which was aimed at the development of alternative environmentally friendly pretreatments to chromium for Tinplate food can applications. A commercial Tinplate was used as substrate. Chromium, titanium, zirconium, cerium, and oxalate-based pretreatments were studied. The characterization of the pretreated Tinplate specimens was carried out using scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS) techniques. The corrosion behavior of the pretreatments was evaluated using electrochemical measurements and exposure tests in several synthetic media. The results obtained led to the conclusion that, among the different pretreatments studied, the best performance was obtained with titanium and cerium compounds.

Corrosion protection properties of cerium layers formed on Tinplate
Corrosion Science, 2004Co-Authors: N. Mora, Emilio Cano, J.l. Polo, J. M. Puente, J. M. BastidasAbstract:Abstract Corrosion protection properties of cerium-passivated, unpassivated and chromium-passivated Tinplates in contact with a 0.1 M citric-citrate buffer solution were studied using polarisation (DC) and electrochemical impedance spectroscopy (EIS) methods. The morphology and composition of the passive layer were studied using scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS) in conjunction with argon-ion sputtering. Cerium-passivated Tinplate showed similar corrosion properties to chromium-passivated Tinplate in DC measurements, while the latter yielded the best corrosion resistance results in EIS measurements. SEM and EDX illustrated spherical particles with iron, cerium and tin contributions. XPS measurements indicated that the cerium-rich coating was a hydrated oxide with a composition of cerium(III): Ce(OH) 3 and cerium(IV): CeO 2 and Ce(OH) 4 .

Environmentally friendly coated Tinplate for food cans
Europace, 2004Co-Authors: N Cristofaro, J. M. Bastidas, J. M. Puente Martinez, J. A. Catala, E. AlmeidaAbstract:Dichromate passivation treatment has been the treatment of choice for Tinplate for over fifty years. It provides excellent corrosion protection, very good lacquer backing and imparts good corrosion resistance to sulphide staining by certain foods. However the recognition that chromium in the hexavalent state is both toxic and carcinogenic has lead to a search for alternative non-toxic coating systems. In the first part of the work, at the industrial plant of Aceralia, Arcelor Group, Spain, was produced a coil of Tinplate without the application of passivation treatment. This material was used as base material for producing Cr-free passivation treatments. Several Cr-free electrolytes were employed to produce passivation films on Tinplate. The treatments using Ti-salt, Ce-salt, oxalate salt and Zr salt were carried out using the parameters selected during the laboratory experiments that are summarised in the following table:
