In this study, linear polarization resistance (LPR) of cathodic pulse electrodeposited graphene- Nickel-Molybdenum coating is optimized by design of experiments approach (central composite design). Applied current density (i), cathodic pulse durations (Ton) and total electrodeposition time (Ttotal) are selected as the substantial factors. The best prediction model proposes a definitive linear relation without any significant interaction of the LPR by analysis of variance. The best value of LPR is achieved equal to 1406KΩ.cm2, obtaining at i of 137.5 A/cm2, Ton of 45.5 ms and Ttotal equal to 315 s. Polarization test is carried out to determine corrosion behavior of the coating. It shows...
