Carob seed oil: an efficient inhibitor of C38 steel corrosion in hydrochloric acid [PDF]

International Journal of Industrial Chemistry, 2012
AbstractBackgroundThe carob seed oil (CO) was tested as inhibitor of the corrosion of C38 steel in 1 M HCl by weight loss and electrochemical measurements. The extract was found to inhibit the corrosion of C38 steel in 1 M HCl.ResultsThe results of the study reveal that the inhibition efficiency of CO depends on its concentration and attains ...
