The purpose of the work was to investigate the effectiveness of zinc-phosphorus-organic inhibitors during metal storage using gravimetric, visual and electrochemical methods. It was established by the conducted research that inhibitor EKTOKAIL-800-1 causes passivation of steel in model solution which is expressed the stronger the higher concentration of inhibitor and is a cathode inhibitor. OPTION-313-1 inhibitor is a mixed type inhibitor that increases overstressing of the anodic process and simultaneously overstressing of hydrogen in the model solution. Under atmospheric corrosion conditions the cathodic inhibitor EKTOKAIL-800-1 is more effective, providing 30.4% protective action coefficient, on the basis of which it can be recommended for steel preservation during storage in atmospheric conditions.
