ABSTRACT
Purpose: The purpose of this study was to investigate the performances of two inhibitors in controlling corrosion of steel products in an industrial/marine atmosphere.
Design/methodology/approach: Corrosion rates were determined by weight loss measurements. At certain periods of atmospheric exposure, the (disc shaped) specimens were retrieved and studied by SEM and EDS surface analysis techniques.
Findings: Both inhibitors were effective against the corrosion of steel in the early stages of the atmospheric exposure (for about two months). With further exposure to the atmosphere, their inhibition effectiveness deteriorated and was totally lost within four months. Analysis of the specimens before exposure showed that the inhibitor film was thin for both treatments and the unexposed treated surface for both inhibitors appeared similar to the untreated unexposed specimen surface. Characterization of the specimens at different exposure periods showed a smaller number of corrosion blisters had formed on surfaces treated with dicyclohexylamine nitrite and sodium benzoate than was the case on untreated specimens.
