摘要

In this work, imidazole (IMZ) is evaluated as a corrosion inhibitor for archaeological steel associated with wood in 10% PEG-200 solution. Inhibitory properties were characterized by electrochemical measurements and morphological analysis, while fungicidal power was monitored by natural aging. The results showed that IMZ is a mixed-type inhibitor with an efficacy of 99.5%, which improves with time, of which 32 °C proved to be the optimum temperature. In impregnation, IMZ preserved the original appearance of the nail while minimizing wood mineralization, although its biocidal power remained insufficient.
