Abstract

Inhibition action of Neem leaves (Azadirachta Indica) extract on the corrosion of 304 stainless steel in 1.0M sulphuric acid solution has been investigated. The investigations were carried out using weight loss method and Scanning Election Microscopy (SEM) analysis. The results showed that the corrosion inhibition efficiency increases with increase in concentration of Neem leaves extract while it decreases with increase of temperature. SEM images indicated that the metal surface was in a better condition in the presence of inhibitor than the specimen exposed in the absence of the inhibitor. Results confirmed that Neem leaves extract acts as an efficient green corrosion inhibitor for 304 stainless steel in 1.0M sulphuric acid solution
