| Abstract: | The corrosion inhibition behaviors of 316L steel using the sodium diethyl dithiocarbamate(SDDTC) compound in simulated crude oil solution were studied in the absence and presence of zinc sulfate or sodium chromate with different combinations.Experiment results showed that in the environments of high acidity and high concentrations of chloride ions the SDDTC compound could well inhibit the corrosion of 316L steel.The good synergic effects on the corrosion inhibition of 316L steel by additions of either zinc sulfate or sodium chromate into SDDTC compound were indicated in this study,which is of great significance and importance in practical applications. |
