THE EFFECT OF ENVIRONMENT ON CORROSION

In this research project, the various nail were subjected to six environments so as to check the effect of the environments on corrosion of the nails. Two sets of nails were used; normal nail and concrete nail. Six of each type while the other not coated. The research was carried out in the physical chemical laboratory of the institute of management and technology. The environments used are acidic solution, alkaline solution, salt solution, boiled water, air medium and lubricating oil medium, which served as a control medium. It was observed from the graphs of the weight of metal against time, that acidic environment gave rise to corrosion at a faster rate that other environment. It was also observed that normal nails gave rise to corrosion at a faster rate than concrete nail. Coating of metals was also concluded to be a method of preventing the rate of corrosion of metals even though it does not stop corrosion.
