“…With the increasingly serious global resource crisis, light metal materials represented by Mg alloys are highly favored. However, the standard electrode potential of Mg is −2.37 V/SCE [ 4 ], indicating a strong tendency of corrosion [ 5 ]. Moreover, when compared to Ti and Al alloys having compact passive surface film, a less corrosion-resistant film, consisting of internal Mg-O and external porous Mg(OH) 2 layers, is generated on the Mg surface [ 6 ].…”

Magnesium (Mg) and its alloys, which have good mechanical properties and damping capacities, are considered as potential candidate materials in the industrial field. Nevertheless, fast corrosion is the main obstacle that seriously hinders its wide applications. Surface modification is an available method to avoid the contact between corrosive media and Mg substrates, thus extending the service life of Mg-based materials. Generally, manufacturing a dense and stable coating as physical barriers can effectively inhibit the corrosion of Mg substrates; however, in some complex service environments, physical barrier coating only may not satisfy the long-term service of Mg alloys. In this case, it is very important to endow the coating with suitable functional characteristics, such as superhydrophobic and self-healing properties. In this review, the various surface treatments reported are presented first, followed by the methods employed for developing superhydrophobic surfaces with micro/nanostructuring, and an overview of the various advanced self-healing coatings, devolved on Mg alloys in the past decade, is further summarized. The corresponding preparation strategies and protection mechanisms of functional coatings are further discussed. A potential research direction is also briefly proposed to help guide functional strategies and inspire further innovations. It is hoped that the summary of this paper will be helpful to the surface modification of Mg alloys and promote the further development of this emerging research field.

“…As a severely destructive phenomenon, metal corrosion generally occurs in all metal-relevant fields, including construction, transportation, microelectronics, mechanical engineering industries, etc., resulting in enormous economic losses and potential safety concerns. − Various strategies have been developed to mitigate corrosion issues on the basis of metal passivation and physical isolation. − Among those, polymeric coating is one of the most ubiquitous methods to overcome corrosion activities by limiting the interaction between metallic substrates and aggressive media . Although effective, the coating is susceptible to suffer damages during the application process, possibly causing catastrophic failure of the entire protective layer.…”

Synergetic self-healing anticorrosion behaviors, by forming a self-assembly protective layer and repairing coating passive barrier, exhibit great potential in handling the notorious metal corrosion phenomenon. Herein, we developed a nanofiber-supported anticorrosion coating with synergistic protection effects of both self-healing and active corrosion inhibition, via a facile electrospinning combined coating technique. Polycaprolactone (PCL) nanofiber integrated with 2-mecapobenzothiazole-loaded halloysite nanotubes (HNTs-MBT) is directly deposited on the surface of metal substrate, forming an interconnected fiber network framework. The encapsulated corrosion inhibitor MBT can be released by a pH-triggered manner to realize instant corrosion protections. Additionally, coating defects could be repeatedly repaired by continuous polymer fiber upon heat treatment and the anticorrosion efficiency effectively remained, even after three cycles of damage–healing. Moreover, the repaired coating also exhibited durable anticorrosion performance, mainly attributed to the synergetic effects of both thermal-triggered bulk healing and active corrosion inhibition. This type of dual-functional coating provides efficient anticorrosive performances and may show great promise in long-term corrosion protection.
