“…The coating could effectively block the penetration of chloride ions to the surface of the Mg substrate, and significantly improve the corrosion resistance of the Mg alloy. Gao et al [116] used GO to modulate the sol-gel process to prepare sol-gel films with a layered structure. Sol particles were efficiently and densely cross-linked along the GO.…”

Magnesium alloys are low in density, high in strength and non-toxic, nevertheless, their industrial application is substantially limited owing to their low electrode potential and susceptibility to corrosion. Surface and coating technology is widely used to improve their corrosion resistance. Graphene is one candidate material for anti-corrosion coatings because of its high aspect ratio, outstanding chemical resistance and good physical resistance. Its good barrier properties mean that graphene may have a wide range of applications in magnesium alloy coatings. This paper reviews (i) the potential of graphene for anti-corrosion coatings, (ii) the production methods and types of graphene anti-corrosion coatings, (iii) their properties, (iv) the protection mechanisms and (v) the future development trends of graphene-based corrosion protective coatings on magnesium alloys.

“…Graphene oxide (GO) is a carbon-based nanomaterial characterized by different oxygen functional groups (such -OH and -COOH) on its basal planes and edges and has received a lot of attention in coating applications as its functional groups ensure its strong compatibility with matrices and additives. Additionally, GO has a great barrier property because of its high aspect-ratio flake-like structure [73]. The effects of GO-filled sol-gel sealing on the corrosion resistance and paint adhesion of anodized aluminum were investigated by Ye et al.…”

Alkoxysilanes represent a class of molecules widely employed to achieve the preparation of plenty of functional surfaces by easy, cost-effective and eco-friendly sol–gel methods. In this regard, the advancements of research activities include the proper design of film/patterns/brushes, by starting from opportune alkoxysilane and/or other metal/metalloid precursors, in order to obtain efficient innovative and homogenous functional surfaces showing implemented properties by means of the simple and eco-friendly sol–gel method. Therefore, in light of these aspects, the employment of opportune functional alkoxysilanes, either in combination with other nanofillers or molecules, is a key step for the design, and development of sol–gel based nanohybrid or nanocomposite coatings suitable for different surface properties implementation and applications, spanning from blue-growth sector to smart and technical textiles, from biomedicine to building and cultural heritages, from environmental remediation to catalysis. Some of the most relevant and explicative examples of these innovative and sustainable sol–gel based coatings will be described in this chapter.

“…This type of material has unique characteristics that are easily recognizable (Huang et In the measured Raman spectrum (Fig. 2), it can be observed that there are two characteristic peaks located at 1359.23 cm -1 and 1592.57 cm -1 (Gao et al, 2021;Sun et al, 2019). Nano-carbon materials usually contain two obvious Raman peaks during research.…”

The uneven surface roughness observed in the electro-spark deposition (ESD) process can be attributed to the unsteady pulsed electrical energy. ESD coating frequently needs to be processed in order to achieve higher surface quality. The surface of the coating undergoes processing techniques such as grinding, ultrasonic processing, and rolling. Because some coatings are hard and the surface hardness is uneven, surface processing is complicated. When a grinder is used for processing, the coating thickness is not easy to control. The product performance is uneven. When non-metallic coatings are used, it can enhance the surface quality of the coating. This study used a composite coating of sodium silicate and lubricating particles. Three coating schemes were studied. Graphene oxide (GO) gel and sodium silicate composite coating have the best overall performance. It can effectively improve the surface quality of the coating, with less roughness and better wear resistance. Graphene oxide gel is used to solve the problem of lubricating particle agglomeration. When it was actually applied to the SKH51 layer, the surface roughness Ra was reduced from 1.086µm to 0.113µm. It is effective in reducing friction and wear.
