Abstract A nanometric (thickness <= 200 nm) composite hybrid coating consisting of alternating laminate layers of aluminium and titanium oxides deposited by atomic layer deposition (ALD) onto a thin graphene layer of reduced graphene oxide (rGO) nanoplatelets applied on AISI 304 stainless steel, was developed and its electrochemical properties were studied. The rGO by itself has not revealed significant effects in terms of protection, whereas the laminate reinforced the passivity by decreasing the passive current. The best performance was obtained by the complete system, in which the rGO film acts as a primer for the anchoring of the ceramic layer, as a barrier for corrosive ions, and as a shield for local electrical fields if these are generated by starting local corrosion, thus, decreases the tendency to metastable pitting.
