Abstract
Biofilm is one of the main factors that influence metal corrosion in seawater environment. According to the structure and property of biofilm, a natural biopolymeric gel,calcium alginate(an extracellular biopolymer containing carboxylate functional groups) can deposite on metal surfaces to form films. Corrosion behavior of alloyed steel E 2, 10CrMoAl and 18_8 stainless steel were studied in simulated biofilm environment by various electrochemical methods,including measurements of the corrosion potential,polarization curves,galvanic current and electrochemical impedance.The results show that such an approach is informative to reveal “how” and “to what extent” biofilm can influence the metal corrosion process.
