“…Nyquist plot in Figure 9 shows larger diameter capacitive loops for CoG (0.15 wt%) and the bode plot in Figure 10 shows higher impedance modulus at low frequency, 18,19 which reconfirms that the CoG (0.15 wt%) coating exhibits better corrosion resistance than the other two coatings. When comparing the corrosion rate between CoG (0.15 wt%) and CoG (0.45 wt%) nanocomposite coatings, CoG (0.15 wt%) exhibits better corrosion resistance.…”

“…But, increasing the GO compositions induced a galvanic coupling between the metal and GO, causing drastic reduction in the corrosion behavior. Even though various reports state that the metal–graphene/GO composite improves the corrosion and wear-resistant behavior when compared to the metallic coatings, 11,18 ratio of the metal-to-GO/GO composition has a significant effect on the enhancement of functional properties.…”

Cobalt–graphene nanocomposite coatings possess unique mechanical and tribological properties which attract researchers to explore its potential for various industrial applications. This research work presents the investigation on cobalt–graphene nanocomposite coatings, with two different graphene compositions cobalt–graphene (0.15 and 0.45 wt%) prepared by pulsed electrodeposition from aqueous bath involving cobalt chloride, trisodium citrate, and citric acid on low carbon steel substrate. Studies on coating morphology, microhardness, tribological characteristics such as wear and corrosion for the cobalt–graphene nanocomposite coatings were reported. Cobalt–graphene (0.45 wt%) nanocomposite coating which exhibits low wear rate in all load conditions due to the self-lubricating property of graphene and cobalt–graphene (0.15 wt%) nanocomposite coating shows higher corrosion resistance due to its layered cauliflower surface morphology.

Photocathodic protection coatings have been widely applied in various areas such as ship and architectural protection, or chemical industry. In this work, a composite of titanium dioxide loaded with reduced graphene oxide (RGO/TiO2) was prepared and used as filler on waterborne polyacrylate (PA) coating to reinforce the metal protection against corrosion. Compared with the current filler of zinc phosphate used for anticorrosive coating, the photoelectrochemical properties of RGO/TiO2‐PA coating exhibit improved photocathodic protection under visible light illumination since RGO/TiO2 composite has significant superiority in enhancing metal protection due to its dispersion, micropore blocking ability, and photoelectrochemical conversion performance. The mechanism of anticorrosion reinforcement of RGO/TiO2‐PA coating was hypothesized that graphene provides an extrabarrier layer to obstruct corrosive in dark condition and photocathodic protection under lighting. © 2019 Wiley Periodicals, Inc.

In this paper, four composite coatings of nano-SnS/polyvinylbutyral (PVB), nano-MoS2/PVB, nano-SnS-Zn/PVB, and nano-MoS2-Zn/PVB were prepared, and their anti-corrosion mechanism was analyzed by experimental and theoretical calculations. The results of the electrochemical experiments show that the effect of nano-MoS2 on the corrosion protection performance of PVB coating is better than that of nano-SnS in 3% NaCl solution, and that the addition of Zn further enhances this effect, which is consistent with the results of weight loss measurements. Furthermore, the observation of the corrosion matrix by the field emission scanning electron microscope (FESEM) further confirmed the above conclusion. At last, the molecular dynamics (MD) simulation were carried out to investigate the anti-corrosion mechanism of the nanofillers/PVB composites for the copper surface. The results show that both nano-SnS and nano-MoS2 are adsorbed strongly on the copper surface, and the binding energy of nano-MoS2 is larger than that of nano-SnS.
