“…It has been reported that air drying after immersion in a 5% NaCl solution drastically reduces the corrosion current of a zinc material. This decrease is attributed to the formation of a more compact corrosion products film as a result of drying [10]. In the cathodic curves, however, there exist a clear reduction in the values of the current density, from the untreated sample to the chromated one, which is exactly of an order of magnitude and that can be confirmed with the i corr values from Table 2, calculated with the potentiostat software.…”

Conventional weight loss tests and both DC and AC electrochemical techniques were used to study if an organic inhibitor containing an alkanolamine salt of a polycarboxylic acid can substitute toxic coatings as chromating and certain phosphating procedures in the protection of galvanized steel. The electrolyte used was a 0.5 M aerated NaCl solution. All tests gave concordant results, indicating that the chromate-free organic inhibitor does protect galvanized steel in this environment, even though the provided protection was less than that of the chromate conversion coating. It was observed that, after a moderate initial attack, the corrosion rate diminishes due to the appearance and growth of passivating corrosion products layers, mainly constituted by zinc hydroxychloride (Zn 5 (OH) 8 CI 2 · H 2 O) and two varieties of zinc hydroxide, among other crystalline compounds.

Abstract:The galvannealed coating with different Fe contents were prepared by controlling the galvannealed process parameters of hot-dip galvanized high-strength IF steel sheet, and analyzed the influence of Fe contents on the corrosion resistance of galvannealed coating. The results show that the corrosion resistance of galvannealed coating increased with the Fe content, and it was also influenced by the phase structure and the proportion of different phases in the galvannealed coating. At the same galvannealed temperature, along with the prolongation of galvannealed time, the initiative corrosion potential of galvannealed coating changed little. The compact Γ 1 phase in galvannealed coating could improve the corrosion resistance effectively. At the same galvannealed time, the corrosion resistance of galvannealed coating was better, when the galvannealed temperature was higher.
