摘要

The effectiveness of poly (2-acrylamido-2-methylpropane sulfonic acid) (PAMPS) and copolymerswith acrylic acid (AA) and acrylamide (AM) magnetic nanogels as protective corrosion of CS inreaction with water by (EIS), (EFM) and tafel polarization method. Polarization method demonstratedthat all the polymers are mixed inhibitor type. (EIS) Electrochemical impedance given that theattendance of these investigated polymers declines the double layer capacitance and improvement thecharge transfer resistance. The polymers adsorption on surface of steel was follow isotherm Temkin.The morphology of the CS surface was examining by (EDX) energy dispersive X-ray and (SEM)scanning electron microscope. The data obtain showed improvement in efficiencies for inhibition withraising the dose of inhibitor.
