Abstract
The nickel hydroxide-graphene oxide (Ni(OH)2-GO) composite coating was facilely formed on the 316 stainless steel (SS) by a pulse current electrodeposition method. The aggregation of Ni(OH)2 particles and GO in the deposition process resulted in the formation of a compact composite coating on the SS substrate. The compact composite coating provided an excellent barrier against corrosion of the SS as the corrosion inhibition efficiency and protection efficiency reached 97.1% and 98.7%, respectively. In addition, the micro-tribological test by AFM demonstrated that the coatings greatly decreased the friction on the SS surface. The lubrication of the coatings strongly depended on their compositions.
