BABY, Grace; RAJENDRAN, Susai; JOHNSIRANI, V.    AL-HASHEM, Abdulhameed. Influence of Zinc Sulphate on the Corrosion Resistance of L80 Alloy Immersed in Sea Water in the Absence and Presence of Sodium Potassium Tartrate and Trisodium Citrate. []. , 38, 6, pp.401-414. ISSN 0872-1904.  https://doi.org/10.4152/pea.202006401.

In cooling water systems, seawater can be used. L 80 can be used as a pipeline for carrying sea water. However, this alloy will undergo corrosion. Corrosion can be prevented by the addition of inhibitors such as sodium potassium tartrate (SPT), trisodium citrate (TSC) and zinc sulphate. Corrosion resistance of L 80 alloy in sea water, in the absence and presence of the above inhibitors, has been evaluated by polarization study and AC impedance spectra. It was observed that SPT and TSC show better inhibition efficiency in the presence of Zn 2+. Further, it was found that the SPT-Zn system is better than the TSC-Zn system
