Resumen:
The early stages of bacterial settlement on 70:30 copper nickel alloy was followed by scanning electron microscopy. Two strains of marine bacteria (Pseudomonas sp and Vibrio alginolyticus) isolated from polluted harbour sea water were used. The corrosion behaviour of the alloy was studied through corrosion potential measurements made in sterile and contaminated sea water. According to the authors' results, microbiological colonisation of the metal surface occurs within the first 24 hours for the two bacteria used. Well defined microbial colonies with localised corrosion underneath were seen by scanning electron microscope after short periods of exposure. Corrosion attack seems to be closely related to passive film modification by the bacterial settlement
