Caratterizzazione della resistenza a corrosione di leghe ferrose in liquidi ionici a base imidazolo,

The possibility to use ionic liquids (ILs) in several industrial applications, from galvanic to electronics, to CO2 capture in combustion processes, requires a deeper understanding of the compatibility of the ILs of major interest with metallic materials that currently compose industrial plants. This work proposes the evaluation of the corrosion behavior of a carbon steel (API 5L X52) and a stainless steel (AISI 316) in presence of methyl imidazolium based ILs. The analysis focuses on the dependence of ILs corrosiveness on their chemical formulation, with particular reference to the anion composition and to the chain length of the imidazolium cation.
