Abstract

Abstract : The effects of cysteine (Cys) and l -methionine (l -Met) on copper corrosion inhibition were examined in 1 M HNO3 solution for short and long exposure times. Abstract : The effects of cysteine (Cys) and l -methionine (l -Met) on copper corrosion inhibition were examined in 1 M HNO3 solution for short and long exposure times. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) were used. The EIS determined the potential for zero charges of copper (PZC) in the inhibitor solution. SEM and AFM have been used to study material surfaces. Energy-dispersive X-ray spectroscopy (EDS) was used to identify surface elemental composition. DFT and molecular dynamics simulations explored the interaction between protonated amino acids and aggressive media anions on a copper (111) surface.
