چکیده
|
The influence of environment and physical parameters on c0.12%mn1.02%si0.29% hle steel steel corrosion damage behaviour in nacl solutions was studied using weight loss,ph evolution at 300k to 370k,electro-exchanges,and passivity. herein,the results show that the corrosion rate changes versus type of thermal treatment and cooling fluid,solution concentration,shape,size and cooling speed of the samples. the resolution of nernst equation proves that the increase in temperature has a direct effect on hydrogen potential of the solution,current and corrosion potential of the metal. moreover,the inhibition efficiency was determined by theoretical calculation using mechanical molecular and semi-empirical method. these results guided us to conclude that the inhibitor,which has low electronegativity than c0.12%mn1.02%si0.29% steel has good efficiency.
