Abstract

Abstract. The corrosion behaviour of SR355JR and S355J2 carbon steels exposed to different seawaters (Black, Aegean and Mediterranean Sea) has been investigated by polarization measurements. The corresponding corrosion parameters were calculated. Micrographic images before and after immersion in the used seawaters corrosive medium were obtained. X-ray diffraction and ponderomotive methods respectively were used to determine the influence of the corrosion process on the crystal structure and specific magnetization of the studied steels.

 

Resumen. En este estudio se investigó el comportamiento a la corrosión de los aceros al carbono SR355JR y S355J2 expuestos a diferentes aguas marinas (Mar Negro, Mar Egeo y Mar Mediterráneo) mediante mediciones de polarización. Se calcularon los parámetros de corrosión correspondientes. Se obtuvieron imágenes micrográficas antes y después de la inmersión en el medio corrosivo de las aguas marinas utilizadas. Para determinar la influencia del proceso de corrosión en la estructura cristalina y la magnetización específica de los aceros estudiados se utilizaron los métodos de difracción de rayos X y ponderomotivos respectivamente.
