Hydrogenation of steel products in the electrochemical processes occurs to some extent in all stages of coating. The decisive contribution in the hydrogenation of steel is galvanized by itself, however, the influence of preliminary operations like degreasing and pickling also are considered as sources of hydrogen embrittlement. In the literature, numerous previous studies are aimed on the effect of deformation on the corrosion behavior of zinc coating, however limited to the specific treatment of corrosion properties leaving aside the possible hydrogen trapping. Embrittlement can occur when hydrogen is released during etching process, absorbed by the steel and being trapped at the grain boundaries, dislocations, interfaces inclusion / matrix, etc. Normally, at galvanizing temperatures, hydrogen is expelled from steel. But, in some cases as in electrogalvanizing, hydrogen is absorbed in the steel. This paper aims to assess the main variables in the pickling and electrogalvanizing in order to optimize the coating procedure which avoids the possible hydrogen entry into the steel. Besides, some thermal properties of the coatings obtained are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
