Abstract

Abstract: The evaluation of the anti-corrosive performance of polymer composite reinforced with zinc phosphate (DGEBA-DAA-ZP) acts as an effective anti-corrosive coating for 15CDV6 steel in 3wt% NaCl at different exposure times ranging from 60, 120, and 180 days in a salt spray chamber. EIS study revealed that composite formulation (DGEBA-DAA-ZP) acts as strong interface coating. Results showed that magnitude of charge transfer resistance (R_ct) and coating resistance (R_pore) gradually decrease on increasing the exposure time. After 1 h exposure time, DGEBA-DAA-ZP formulation exhibited R_ct and R_pore values of 16.6 kΩ cm² and 6.16 kΩ cm², respectively. However, after 180 days exposure, the R_ct and R_pore values lower to R_ct and R_pore to 4.21 kΩ cm²and 2.25 kΩ cm², respectively. MD simulation study demonstrated that DGEBA-DAA-ZP adsorbed on the Cd surface using its flat orientation. Graphic Abstract: [Figure not available: see fulltext.].
