@Article{, title={USING OLIVE STONE POWDER FOR STEEL CORROSION INHIBITION}, author={Rami Adel Qassim and Sahib Mohammed Mahdi and Jafar Ghani Majeed}, journal={Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة}, volume={22}, number={2 conference proceedings (Part-1)}, pages={1-9}, year={2018}, abstract={corrosion of metals is the most significant and difficult life problems, especially its produce an economical losses, therefore, many researches carried out in various fields in order to reduce the bad effect of corrosion, particularly in acidic environments. Using corrosion inhibitors is one of the methods of prevention corrosion, which come up on organic and inorganic materials, in this study, dried Olive stone powder used as corrosion inhibitor in solutions of hydrochloric acid with concentrations of 0.5, 1 and 1.5 molarity at room temperature, where 10 gm per litter of acid. The corrosion rates of mild steel samples were measured using potentiostat device with reference of calomel electrode. The result shows that corrosion rate reduced by adding the Olive stone powder. The highest inhibition efficiency percent for acid solutions with concentration of 1.5 molarity is 82.9%, while the lowest was 64.1% in the 0.5 molarity solution, and in the 1 molarity solution was 77.6%. The chemical composition of the Olive stone powder is shown to be an organic matter of a high carbon and hydrogen content making a carbonyl compound which has the greatest effect in inhibition corrosion in acidic solutions such as hydrochloric acid.
