Abstract
In this paper, the corrosion and wear-resistant coatings including graphene oxide (GO), reduced graphene oxide (RGO), TiC, and TiB2 as GO/RGO/TiC/TiB2 nanocomposite was applied on Ti–6Al–4V alloy through electrical discharge coating. Characterizations of coatings were accomplished by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), pin on disk, microhardness, potentiodynamic polarization, Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and atomic force microscopy (AFM). Results show not only corrosion resistance of the substrate owing to the barrier layer effect of graphene increase up to 19 times but also the coefficient of friction (COF) can be effectively reduced from 0.35 on the substrate to 0.2 on the coating. These modifications are verifying the positive effect of TiC/TiB2 and graphene in the coating.
