Pure Ni, Ni-MoS2 and Ni-graphene coatings were fabricated on the substrate of quenching & partitioning (QP) steel by electrodeposition from the Watts bath. The hydrogen permeation properties of QP samples with all the electrodeposited coatings were characterized and compared with the galvanized QP steel using electrochemical technique. Results showed that the galvanized coating and the deposited Ni and Ni-based coatings could reduce the hydrogen permeation current. However, the mechanisms of affecting hydrogen permeation for various coatings were different. Furthermore, the diffusion coefficient of hydrogen in each coating was also determined. The slowest kinetics for hydrogen evolution reaction (HER), the largest decrease in the steady-state permeation current density ip∞ and the lowest diffusion coefficient Dc proved that Ni-graphene possibly provides the best protective performance against HE in QP steel.
