- Abstract
- This study evaluates hydrazide derivatives, PEH and PAH, as corrosion inhibitors for N80 steel in acidic conditions. Utilizing a blend of experimental tests and theoretical calculations, including EIS, PDP, SEM, DFTB, and MD simulations, up to 96% inhibition efficiency was attained. Specifically, the PAH compound displayed notable protection. The Langmuir adsorption model confirmed dual adsorption, and theoretical simulations revealed interaction mechanisms. The research provides valuable insights into the formation of covalent bonds between inhibitor molecules and iron atoms, and offers a promising path for the development of advanced corrosion inhibitors suitable for industrial applications.
