摘要

Mild steel is used as main raw material in fabrication of equipment, chief material of construction and fabrication of 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-N-Dimethyl aniline (DMA), Morpholine, Cyclohexyl amine and Hexamethylene imine were tested for mild steel under different corrosive 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. 96-98%. The results obtained from corrosion experiments were supported by surface study carried out by SEM technique.
