EFFECT OF EXPOSURE ANGLE ON THE MARINE ATMOSPHERIC CORROSION OF MILD STEEL

The effect of exposure angle on mild-steel corrosion in a marine atmosphere was assessed, and was found to vary with the angle of exposure, especially above 75o: and approximately- 425% increase in corrosion rate was evident at 180o. A similar trend was observed in the rate of salt accumulation on the test panel. There were positive linear relationships between the angle of exposure and mild- steel corrosion, and between the rate of salt accumulation and the corrosion of the mild steel sample. This suggest that the angle of metal exposure influences salt accumulation, thereby affecting the corrosion rate. Theoretical values for Fe304 content in the corrosion product were in the range 79-89%.
