“…The CVD process was successful in gaining a super-hydrophobic coating at low temperature with enhanced corrosion resistance due to the physical shielding and water-repellent nature of the CNF coating [22]. A polymerized ECH coating without any defects was achieved with the help of plasma-enhanced CVD; the coating thickness increased with the duration of the process and adhesion was better with a coating providing better corrosion prevention [23]. The plasma-enhanced CVD process has less dependency on the substrate temperature; with increasing thermal effects on the substrate, deformation was observed on the magnesium substrate causing defects on the coating and its properties [11].…”

An enormous amount of research is conducted on aluminium alloys on friction stir process, despite magnesium alloy reporting severe weight reduction when compared to aluminium alloys; a very slight amount of research was testified by friction stir processing of magnesium alloys. Magnesium is highly reactive and susceptible to corrosion in the presence of an aggressive environment. This highly corrosive nature of magnesium limits its applications. Surface properties like crystal structure, composition, and micro structure influence the corrosion and wear property of the material. Coating and alloying like laser surface modifications are performed to passivate magnesium surface from corrosion. Coating techniques, however were found to be insufficient in corrosion protection due to coating defects like pores, cracks, etc, and adhesion problems caused due to poor surface preparation of the substrate, and also impurities present in coating which provides micro galvanic cells for corrosion. Current study analyses the detailed overview of different types of Surface modification methods such as Physical vapor deposition, Chemical vapor deposition, Chemical conversion coating, Ion implantation coating techniques and also work focuses on few of Alloying or Surface processing methods such as Laser surface modification namely Laser surface melting, Laser surface cladding, Laser Shot Peening, Laser surface alloying and Friction stir processing (FSP). Friction stir processing a novel method derived from friction stir welding is used as surface modification method, which modifies micro structure, composition of surface layer without changing bulk properties, for enhancing corrosion resistance property. FSP enhances the micro structure and homogenizes but it is also eliminating the breaking up of the brittle- network phases and also cast micro structure imperfections. Indeed FSP can produce particle and fiber-reinforced magnesium-based surface composites. FSP empowers the manufacturing of magnesium by adding additives. Comparison of the different methods of coating and surface modification has been compared with FSP

“…In recent years, surface modification has received growing attention as a means to improve the wear and corrosion resistance of Mg alloys. Such techniques include hydrothermal treatment [5], micro arc oxidation [6,7], vapour deposition [8], sol-gel processing [9], and ion implantation [10]. Among them, hydrothermal treatment is advantageous in that it is simple to operate, has low energy consumption, and is environmentally friendly.…”

Hydrothermal treatment was adopted to address the wear and corrosion problems that are common when using magnesium alloys. Films consisting of magnesium hydroxide and Mg-Al layered double hydroxide (LDH) were formed on the AZ31 Mg alloy via hydrothermal treatment in deionised water and an alkaline solution containing aluminium ions, respectively. It was found that the presence of aluminium and hydroxyl ions in the hydrothermal solution significantly promoted LDH formation. Performance testing for the obtained films showed that their tribological properties and corrosion resistance were significantly improved compared to those of the Mg alloy. Furthermore, the film prepared in an alkaline solution containing aluminium ions exhibited a more stable friction coefficient, a lower wear rate, and a superior corrosion resistance, which were associated with the increased LDH content. This study, therefore, presents a facile and promising method for the development of highly wear-resistant and anti-corrosion surfaces for Mg alloys.
