Study of Amine as Vapour Phase Corrosion Inhibitors for Mild Steel under different aggressive Atmospheric Conditions at high temperature

Mild Steel and their products are main raw material for a strong infrastructure for every country which is the main demand in the race of survival, stabilization, growth and competition for every country. Industrialization and modernization in now a days has made a strong demand of steel and their maintenance but atmospheric corrosion can aggressively accelerate the degradation of metals during their manufacturing, processing, storage and transportation. In these cases, traditional methods to prevent corrosion are not suitable which provides the scope of VPCIs in industries, defense and daily life. Three new vapour phase corrosion inhibitors (VPCI) Triethylamine (TEA), Ethylamine (EA) and N-Ethylaniline (NEA) were tested for mild steel in different atmospheric conditions at 50C by Weight Loss Technique, Eschke test, Salt Spray Method, Sulphur Dioxide (SO2) Test and results of tests were supported by Metallurgical Research Microscopy Technique and SEM Technique.
