Based on the importance of nano particles and metal corrosion, the outstanding features of nano coatings on B- Graded mild steel samples are discussed in the present paper. Besides, in order to control the pitting corrosion and anti- fouling corrosion in case of marine equipment which would be corroded by sea atmosphere, salt water and snow in the sea environment. In this study, the changes in the epoxy based marine coatings was studied with the addition of 1% wt, 2% wt, 4% wt and 6% wt of Aluminium(Al) nano powder whose particle size is ~ 70 nm. Corrosion performance was evaluated by applying these nano coatings on mild steel substrates of size 40X40X5 mm3 and by exposing them to salt water immersion test for a week. Results were observed as with an increasing concentration of Al nano powder, corrosion resistance was improved and mechanical properties as well.
