“…Secondly, increasing the amount of alloying element similarly enhances the strength and reduces the ductility of Zn. However, there are exceptions such as those reported by Tang et al [106], where both strength and ductility of Zn-Cu alloy increased with increasing Cu content, or that of Sun et al [112], where the strength decreased while ductility increased in Zn-Mn alloys with increasing Mn content. These will be examined further in the succeeding discussions.…”

“…The influence of fabrication technique on microstructure will be discussed in the succeeding section. For the Zn-Mn alloy, Sun et al [112] reported that the alloy's mechanical strength decreased and ductility increased with increasing alloy content (i.e., 0.2, 0.4, and 0.6 wt% Mn), contrary to what was typically seen in other biodegradable Zn alloys. They noted that increased Mn additions significantly refined the Zn grains and also increased the presence of the intermetallic, MnZn 13 .…”

Zinc has been identified as one of the most promising biodegradable metals along with magnesium and iron. Zinc appears to address some of the core engineering problems associated with magnesium and iron when applied to biomedical implant applications; hence the increase in the amount of research investigations on the metal in the last few years. In this review, the current state-of-the-art on biodegradable Zn, including recent developments, current opportunities and future directions of research are discussed. The discussions are presented with a specific focus on reviewing the relationships that exist between mechanical properties, biodegradability, and biocompatibility of zinc with alloying and fabrication techniques. This work hopes to guide future studies on biodegradable Zn that will help in advancing this field of research. Statement of Significance (i) The review offers an up-to-date and comprehensive review of the influence of alloying and fabrication technique on mechanical properties, biodegradability and biocompatibility of Zn; (ii) the work cites the most relevant biodegradable Zn fabrication processes including additive manufacturing techniques; (iii) the review includes a listing of research gap and future research directions for the field of biodegradable Zn.

“…And alloying with Mn resulted in a superb elongation compared with other Zn alloys. Apart from the solid solution and refined grain, tensile twin was a key factor affecting the mechanical property of as-extruded Zn-Mn alloys 49 . Although Ca and Sr showed no strengthening effect on Zn in this study, an increased tensile strength of Zn-Ca, Zn-Sr, and Zn-Fe alloys with higher contents were observed elsewhere 16,50 .…”

Alloying design of biodegradable zinc as promising bone implants for load-bearing applications

Magnesium-based biodegradable metals (BMs) as bone implants have better mechanical properties than biodegradable polymers, yet their strength is roughly less than 350 MPa. In this work, binary Zn alloys with alloying elements Mg, Ca, Sr, Li, Mn, Fe, Cu, and Ag respectively, are screened systemically by in vitro and in vivo studies. Li exhibits the most effective strengthening role in Zn, followed by Mg. Alloying leads to accelerated degradation, but adequate mechanical integrity can be expected for Zn alloys when considering bone fracture healing. Adding elements Mg, Ca, Sr and Li into Zn can improve the cytocompatibility, osteogenesis, and osseointegration. Further optimization of the ternary Zn-Li alloy system results in Zn-0.8Li-0.4Mg alloy with the ultimate tensile strength 646.69 ± 12.79 MPa and Zn-0.8Li-0.8Mn alloy with elongation 103.27 ± 20%. In summary, biocompatible Znbased BMs with strength close to pure Ti are promising candidates in orthopedics for loadbearing applications.

Investigation on the Mechanical and Corrosion Properties of ZnMnSr Alloys for Biodegradable Orthopedic Implants

et al. 2022

Zinc‐based alloys with good biocompatibility and corrosion resistance are potential candidates for bioabsorbable implants. Herein, a series of Zn99−x Mn x Sr1 (x = 0.2, 0.3, 0.5, and 0.9 wt%) alloys are investigated using single‐channel vertical extrusion (SCVE) and equal‐channel angular pressing (ECAP) procedures, respectively. It is found that the amount of Mn significantly affects the mechanical properties of alloys. For example, the yield strength, tensile strength, and elongation of Zn–1Sr alloys can reach up to 204.73 ± 3.6 MPa, 244.04 ± 6.45 MPa, and 47.1 ± 3% with 0.99 wt% Mn addition after the SCVE process, which can meet the requirement of orthopedic implant applications. Moreover, the mechanical properties of current alloys are reduced with the combined SCVE + ECAP process, which may be due to more aggregation with the secondary phase within the matrix hcp(Zn). Furthermore, the polarization curves and immersion tests show that the corrosion rate is accelerated for the alloys processed with the combined SCVE + ECAP process (0.34–0.171 mm/y) compared with the ones processed only with SCVE (0.011–0.032 mm/y). The present finds provide a contribution for biodegradable Zn‐based alloys development.
