Abstract

Nine green compounds,including calcium gluconate,zinc gluconate,zinc sulfate,garlic,ACUSOL 445N,OS_15,APG,OCTA and STPP were selected according to the methods of molecule design and function groups prune. The functions of combined corrosion inhibitors mixed by the compounds mentioned above for mild steel in seawater were studied in this work using the methods of polarization curve and weight_loss.The best weight ratio and distinct synergistic effect of calcium gluconate,zinc sulfate and OCTA were studied by Latin experiment. The afgereffects of the best weight ratio corrosoin inhibitor were studied by subsection experiment. In this way, a kind of high effect green corrosion inhibitor was obtained.
