“…The range of the calculated Tafel slopes indicates that the dissolution process of tin-silver alloys is under activation control. [4,16] As can be seen, the corrosion current density i corr shows a regular dependency on both the alloy composition and the solution concentration. The increase of the solution concentration has a pronounced effect on the corrosion current and consequently on the dissolution rate.…”

“…[2] The corrosion resistance of tin can be attributed to a thin surface oxide layer of SnO 2 . [3] Also, it has been reported [4] that in 4.5-8.0 M sulfuric acid solutions, tin dissolves both in the active and partly passive potential region in the bivalent tin oxide (SnO), mostly in an amorphic form. Oxidation to the tetravalent state seems to occur only at high anodic potentials.…”

The electrochemical and passivation properties of three selected binary xSn-Ag (x = 26, 50 and 70 wt%) alloys were studied by means of open-circuit potential variation, potentiodynamic curves and a.c. impedance spectroscopy techniques.The specimens were polarized between −1.0 and 0.5 V versus saturated calomel electrode (SCE) in naturally oxygenated sulfuric acidsolutions of different concentrations The experimental results indicate that i corr increases with increasing either the acid concentration or the Sn content in the solid phase. Electrochemical impedance spectroscopyresults measured at the free corrosion potential confirm that alloy I (26Sn-Ag) characterizes by thicker passive film with higher protective ability compared to the other two samples richer in tin component. The exponential variation of the relative thickness of the surface film on any of the tested samples assumes an almost constant thickness for a thin barrier layer and a much larger outer porous layer that dominates the total film thickness on the alloy.

“…It is obvious that the quantity of electricity consumed through the peak A (Q A ) is greater than that consumed through peak C (Q C ). It is probable that the dissolution soluble products formed during anodic sweep have tended to diffuse into the bulk of the solution before being reduced [25]. Fig.…”

Tin is a chemical element which is represented by the symbol Sn. Tin is most commonly used in the form of tin cans. Food cans mainly store food stuff and used by packaging industry. The corrosion is a major problem in tin cans and a matter of great concern for the corrosion engineers as well as researchers. This article deals with corrosion behaviour of tin cans in different media and its inhibition. Researches which have been done on dissolution of tin in different types of canned products containing hydrochloric acid, tartaric acid, citric acid, maleic acid and formic acid have been described here since acids have a great tendency of dissolving the metal to which they come into contact. It has been found that artificial fruit juices and preservatives augment the rate of corrosion as compared to natural juices and acids. The comparative study of the rate of corrosion in tin cans under different conditions along with the techniques to determine the rate of corrosion has been studied The literature review on a wide range of corrosion inhibitors used to inhibit corrosion has been systematically carried out. The main purpose of this review is to showcase the various cases of corrosion mechanism and inhibition methodologies to combat corrosion of tinplate.
