Sažetak
In this paper we investigated the tendency of carbon steen designated AISI 1018 to begin pitting corrosion in distilled water and in the simulated oilfield brine with and without olive leaf extract (Olea europaea L.) as a novel, environmentally acceptable corrosion inhibitor. The inhibitor concentrations of 50, 100, 150 and 200 mg/l were examined. Measurements were conducted using the method of cyclic polarization in an open system at atmospheric pressure and room temperature. Testing of different states of the carbonic steel surface was conducted by scanning electron microscope. Using the mass loss method, the efficiency of the inhibitor was tested and the adsorption isoterms of olive leaf extract, which describe its behavior on the carbon steel surface, were made.
