Study of Vapour Phase Corrosion Inhibitors for Mild Steel under different Atmospheric Conditions
نویسندگان
چکیده
Mild steel is used as main raw material in fabrication of equipment, chief material of construction and as weapons. During the storage and transportation conditions, it comes in contact with aggressive environment which leads to decrease in mechanical strength. Four different vapor phase corrosion inhibitors (VPCIs) i.e. n-Caprylic acid (CA), nButyric acid (BA), N,N-dimethyl propylene urea (DMPU) and 2-Amino Benzothiazole (ABT) were tested under different atmospheric conditions at 40 C by Weight Loss, Eschke test, Salt Spray and SEM techniques. All the four VPCIs show very high corrosion inhibition efficiency i.e. 79-99 %. The results obtained from corrosion experiments were supported by SEM images.
