| description | Within the framework of this study, Ni-based composite electrochemical coatings (CECs) modified with multilayer graphene oxide (GO) processed using microwave radiation have been deposited. The process of these coatings’ electrodeposition in the potentiodynamic mode has been studied. The structure of Ni–GO and Ni–GO (MW) CECs has been studied using X-ray phase analysis (XPA) and scanning electron microscopy (SEM).It has been shown that the addition of GO into a nickel deposit contributes to the formation of uniform fine-grained coatings. As a result, the microhardness of the Ni–GO (MW) CECs increases by 1.40 times compared to Ni without GO. The corrosion–electrochemical behavior of nickel CECs in 0.5 M H<sub>2</sub>SO<sub>4</sub> solution was researched. It was established that the corrosion rate of the nickel–GO (MW) CEC in 3.5% NaCl decreases by about 1.70 times in contrast to unmodified nickel coatings. This effect is due to the absence of agglomeration of the graphene oxide in the volume of the nickel matrix and the impermeability of GO particles to the corrosive environment. |
