摘要

The aim of study id to investigate the corrosion rate of low carbon steel in a saline aqueous media under different pH values being acidic, neutral and basic one and at different temperatures using weight loss technique. The maximum corrosion rate of low carbon steel was observed in acidic saline solutions which is being lower than those observed in basic one and insignificant in neutral one. It was noted that corrosion rates increased rapidly with increase in temperature and approached a maximum value in acidic media at 50°C. Maximum coating efficiency was 45.5% at pH 5, 0.25 g/L NaCl and 20°C.
