“…In another study, the Mg–1Ca alloy implanted with Zn ions in a metal vacuum arc plasma source had shown better corrosion resistance than Mg–1Ca. Moreover, the cell viability of treated and untreated samples was similar after 1 and 3 days of incubation . Similarly, the corrosion potentials of Hafnium (Hf) ion‐implanted WE43, and neodymium (Nd) ion‐implanted WE43 were enhanced in the SBF when compared to bare WE43.…”

Magnesium (Mg) has emerged as an ideal alternative to the permanent implant materials owing to its enhanced properties such as biodegradation, better mechanical strengths than polymeric biodegradable materials and biocompatibility. It has been under investigation as an implant material both in cardiovascular and orthopedic applications. The use of Mg as an implant material reduces the risk of long-term incompatible interaction of implant with tissues and eliminates the second surgical procedure to remove the implant, thus minimizes the complications. The hurdle in the extensive use of Mg implants is its fast degradation rate, which consequently reduces the mechanical strength to support the implant site. Alloy development, surface treatment, and design modification of implants are the routes that can lead to the improved corrosion resistance of Mg implants and extensive research is going on in all three directions. In this review, the recent trends in the alloying and surface treatment of Mg have been discussed in detail. Additionally, the recent progress in the use of computational models to analyze Mg bioimplants has been given special consideration.

“…At present, a variety of surface modification strategies, such as plasma electrolytic oxidization (PEO) or microarc oxidation (MAO) [12][13][14][15][16], chemical conversion coatings [17][18][19][20][21], ion implantation [11,[22][23][24][25], electrochemical deposition [26][27][28][29][30] and layered double hydroxides (LDHs) [3, 31,32], have been employed to manipulate the degradation of Mg-based implants in vitro and in vivo. However, their practical applications would be impeded by their disadvantages such as the relatively high energy consumption of MAO technology and the porosity of the resultant coating.…”

Magnesium (Mg) and its alloys are considered as ideal biodegradable materials due to their excellent mechanical properties and biocompatibility. In order to improve the surface properties to allow better adaptation to the surrounding tissue of the body, surface modification has played a significant role in satisfying multiple clinical requirements such as corrosion resistance, biocompatibility, and antibacterial ability. Here, layer-by-layer (LbL) self-assembly, which can be applied for biodegradable Mg alloys due to its extensive choice of usable units, holds great promise among all the surface techniques. In this review, the mechanisms of the driving force (i.e., electrostatic interaction, hydrogen bonding, charge transfer interaction and covalent bonding), cuttingedge advances in preparation methods (e.g., dipping, spraying, and spinning) and the functional properties (corrosion resistance, antibacterial activity, and biocompatibility) that could be achieved by the LbL coatings are summarized. A reasonable trend of the potential development of LbL for bio-Mg alloys is also proposed at the end of this article.

“…Unfortunately, the corrosion resistance of magnesium alloys in many engineering applications is insufficient [4,5] and methods such as micro-arc oxidation [6,7], laser cladding [8,9], plasma electrolytic oxidation [10,11] and ion implantation [12][13][14][15] have been proposed to improve the corrosion properties. For example, Zn [16,17], Zr [18], Nd [19], C 2 H 2 [20] and Si [21] ion implantations have been conducted on Mg alloys to improve the surface properties [17,22].…”

Ti, Ni, and Ti/Ni plasma immersion ion implantation is carried out on the AM60 magnesium alloy with a 6 × 1016 ions/cm2 fluence and energy of 35 keV. The corrosion and wear properties of the ion-implanted samples are determined systematically by X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, electrochemical methods and wear tests. A Ni-rich layer composed of α-Mg, Ni2O3, and NiTi2 is formed on the surface after dual Ti/Ni ion implantation, and the ion implantation range is approximately 300 nm. The corrosion resistance of the Ni- and Ti/Ni-implanted AM60 samples is significantly reduced in the 3.5% NaCl solution. However, NiTi2 does not adhere well to the grinding ring during the wear test due to the bonding properties, and the sample implanted with both Ti and Ni shows the best wear resistance.
