“…Recently, the main researches include metal ion such as iron (Fe), cerium (Ce), zinc (Zn), zirconium (Zr), strontium (Sr), as well as the non-metallic ions such as carbon (C), oxygen (O), Nitrogen (N) ( Liu et al, 2017 ; Somasundaram et al, 2018 ; Zhu et al, 2018 ). Jia et al (2018) observed that after implanting Sr ions into Mg alloys, the elastic modulus and hardness are improved, and meanwhile the corrosion potential is increased. Zhu et al (2018) implanted N ions on the surface of AZ31 alloy, followed by magnetron sputtering to generate double-layer amorphous hydrogenated diamond-like carbon (DLC:H)/SiNx, which effectively improves the long-term corrosion resistance of the substrate.…”

Magnesium (Mg) and Mg alloys are considered as potential candidates for biomedical applications because of their high specific strength, low density, and elastic modulus, degradability, good biocompatibility and biomechanical compatibility. However, the rapid corrosion rate of Mg alloys results in premature loss of mechanical integrity, limiting their clinical application in load-bearing parts. Besides, the low strength of Mg alloys restricts their further application. Thus, it is essential to understand the characteristics and influencing factors of mechanical and corrosion behavior, as well as the methods to improve the mechanical performances and corrosion resistance of Mg alloys. This paper reviews the recent progress in elucidating the corrosion mechanism, optimizing the composition, and microstructure, enhancing the mechanical performances, and controlling the degradation rate of Mg alloys. In particular, the research progress of surface modification technology of Mg alloys is emphasized. Finally, the development direction of biomedical Mg alloys in the future is prospected.

“…Besides, there is no abrupt interface and the bonding force is strong, the dimensional size of the treated sample doesn't change after ion implantation [6]. The types of the implanted element are significant to the improvement of surface properties, recently, these are various metal elements have been involved in the modification of biomedical magnesium through ion implantation, including Al [7], Zn [8], Ti [9], Ce [10], Nd [11], Pr [12], Hf [13], Sr [14], Sn [15], Ag [16]. For instance, Al ion implantation was conducted and a gradient surface structure formed on the Mg surface, which greatly reduced its degradation rate in simulated body fluids(SBF) [7].…”

In order to improve the surface properties and satisfy the controlled degradation of biomedical magnesium, Zr ion implantation was conducted on ZK60 magnesium with different doses in the range from 1×10 16 to 5×10 16 ions cm −2 and an accelerating voltage of 40 kV. The Zr ion concentration and displacement damage were simulated by the Stopping and Range of Ions in Matter (SRIM), the surface morphologies, structure, composition, surface mechanical properties and corrosion resistance in simulated body fluid were investigated using atomic force microscope, fieldemission scanning electron microscopy, X-ray photoelectron spectroscopy, nano-indentation, electrochemical experiments and the hydrogen evolution tests. The results indicated that the distribution of the implanted Zr concentration and displacement damage can be accurately adjusted through controlling the implanted doses, the ZK60 surface becomes smoother after Zr ion implantation along with the reduced roughness at specific doses. When the dose is 2×10 16 ions cm −2 , a gradient modified layer mainly composed of MgO, ZrO 2 and Zr, in thickness greater than 120 nm, formed on the near-surface of ZK60 after Zr ion implantation. Besides, it also possesses the largest hardness and modulus, the lowest corrosion current density and hydrogen evolution volume, indicating that the surface mechanical properties and corrosion resistance of ZK60 can be effectively improved by Zr ion implantation. Additionally, the modification mechanisms were also discussed.
