Study on corrosion inhibition performance of 4,5-diamino-6-hydroxy-2-mercapto-pyrimidine film on copper against NaCl solution

4,5-diamino-6-hydroxy-2-mercapto-pyrimidine (MPD) molecule was adsorbed at the copper surface via self-assembly method,and its corrosion inhibition performance in 3.5% (mass fraction) NaCl solution was investigated by electrochemical polarization,electrochemical impedance spectroscopy (EIS),and Rama...
