Corrosion of aluminium,zinc and mild-steel in an industrial atmosphere

摘要

Corrosion rate of metals,atmospheric salinity and sulphation rate have been determined at Vapi Industrial Complex situated in South Gujarat.Monthly corrosion rate is in the order of aluminium < zinc < mild-steel (MS);whereas yearly rate follows the same trend.Mild-steel exposed vertically suffer less corrosion than those exposed at an angle of 45~o.
