Resumen en inglés Galvanic corrosion of steel-copper couple in saline petroleum wastewater in the absence and presence of curcuma extract as corrosion inhibitor was studied as a function of temperature, velocity, and inhibitor concentration. The electrochemical polarization technique was used to evaluate the corrosion parameters. Corrosion currents densities increase with temperature and velocity, while it decreases with inhibitor concentrations. In this investigation, a theoretical model equation was used to analyze the shape of polarization curves. Microsoft Excel program was used to find the galvanic current and galvanic potential. Theoretical results agreed with experimental one
