摘要：
The solid lubricant graphene coating was prepared by adding aqueous dispersion of graphene into two-component waterborne epoxy coatings. The electrochemical corrosion behavior and failure process were investigated by potentiodynamic polarization curve and electrochemical impedance spectroscopy in simulated seawater (3.5% NaCl solution). The sliding friction and wear behavior, wear scar morphology and wear mechanism of the three graphene-epoxy coatings were analyzed by UMT-3 tribology tester in dry condition and seawater environment, respectively. Results indicated that the graphene obviously improved the coating resistance and charge transfer resistance of the epoxy coating, also reduced the friction coefficient and wear rate of the epoxy coating, Friction coefficient and wear rate of graphene-epoxy coating in seawater were lower than that in dry condition. ©, 2015, Science Press.
