Abstract

A kind of environment-friendly compound corrosion inhibitor has been made from sodium tungstate, sodium silicate, calcium gluconate, sodium polyphosphate and zinc sulfate. The inhibition capability of the corrosion inhibitor in seawater for carbon steel is carried out by weight-loss method and electrochemical method. The effect of different inhibitors concentration on the corrosion efficiency is also studied. The results show that the presence of these compounds in seawater suppresses cathodic processes and when the dosage of sodium tungstate is 80mg/L, sodium silicate is 20mg/L , calcium gluconate is 40mg/L, sodium polyphosphate is 60mg/L and zinc sulfate is 60mg/L , the corrosion inhibition effects of carbon steel are pretty good. Carbon steel corrosion inhibition efficiency reaches 92.53% in seawater for 15 days.
