A polyaniline-graphene oxide (PANI-GO) composite coating was prepared on the 316 stainless steel (SS) by a pulse current codeposition method. Agglomeration of aniline and graphene oxide occurred during the deposition process and formed a compact coating on the SS surface. The compact structure showed an excellent corrosion resistance. The corrosion inhibition efficiency and protection efficiency of the PANI-GO composite coating reached 98.4% and 993%, respectively. In addition, the deposition parameters had an obvious effect on the corrosion resistance of PANI-GO composite coatings due to changes of their porosity and wettability. (C) 2017 Elsevier B.V.
