ABSTRACT

 

Progressive corrosion rate from one to twelve months of aluminium, zinc and mild-steel (MS) as well as the atmospheric salinity rate have been determined under outdoor conditions of exposure at Goima-village situated in South Gujarat. Aluminium, zinc and mild-steel plates exposed during July-1995 indicates corrosion rate of 4.2 (1.9 mm/y), 76 (12.9 mm/y) and 1400 (243.3 mm/y) mg/sq.dm for one months exposure period and 109.7 (4.0 mm/y), 244 (3.4 mm/y) and 15,200 (217.0 mm/y) mg/sq.dm for aluminium, zinc and mild-steel respectively for twelve months exposure period . Mild-steel panels exposed vertically suffer less corrosion than those exposed at an angle of 45

 

Keywords : Rural atmosphere, Salinity rate, Corrosion rate, Aluminium, Zinc, Mild-steel.
