“…The in vitro corrosion behavior of pure Zn in different corrosive mediums has been extensively investigated by researchers [ 85 , 256 , [267] , [268] , [269] ]. For example, the corrosion behavior of pure Zn in two corrosive solutions, PBS and RSS, and two natural body fluids, human plasma and whole blood, was first reported by Torne et al [ 256 ] and their results indicated that corrosion rates decreased with immersion time for plasma and whole blood, while they increased during immersion in PBS and RSS.…”

“…The influence of diameter on the in vitro corrosion performance of as-extruded pure Zn wires in HBSS was also investigated by Guo et al [ 268 ] and their results showed that during 30 d immersion, a 3 mm Zn wire exhibited much better corrosion resistance than a 0.3 mm Zn wire. Recently, in vitro degradation of pure Zn was investigated by Liu et al [ 267 ] by immersing it for 4 weeks in bovine serum albumin (BSA). Their results indicated that the adsorption of BSA protected the substrate from dissolution on the first day, but chelation of BSA and Zn 2+ increased the corrosion rates over 3–7 d immersion.…”

Biodegradable metals (BMs) gradually degrade in vivo by releasing corrosion products once exposed to the physiological environment in the body. Complete dissolution of biodegradable implants assists tissue healing, with no implant residues in the surrounding tissues. In recent years, three classes of BMs have been extensively investigated, including magnesium (Mg)-based, iron (Fe)-based, and zinc (Zn)-based BMs. Among these three BMs, Mg-based materials have undergone the most clinical trials. However, Mg-based BMs generally exhibit faster degradation rates, which may not match the healing periods for bone tissue, whereas Fe-based BMs exhibit slower and less complete in vivo degradation. Zn-based BMs are now considered a new class of BMs due to their intermediate degradation rates, which fall between those of Mg-based BMs and Fe-based BMs, thus requiring extensive research to validate their suitability for biomedical applications. In the present study, recent research and development on Zn-based BMs are reviewed in conjunction with discussion of their advantages and limitations in relation to existing BMs. The underlying roles of alloy composition, microstructure, and processing technique on the mechanical and corrosion properties of Zn-based BMs are also discussed.

“…The positive effects of CO 3 2− and PO 4 3− are attributed to the formation of carbonate or phosphate on the surface of the alloy to prevent corrosion. Furthermore, protein is also responsible for the increase in corrosion rate [13], it can be seen from figure 1(e) that the corrosion rate of the alloy in DMEMp with serum added is higher than that in DMEM.…”

“…These inorganic components largely govern the corrosion behavior of the alloy in biological conditions [12]. In the human blood serum, protein concentration is about 60-80 g l −1 , which is considered to greatly impact on corrosion behavior of implant material [13]. Therefore, it is necessary to investigate the biodegradation behaviors of Zn-0.8Li-0.2Ag alloy in different simulated body fluids, and its effect on cytotoxicity and antibacterial properties.…”

Rolled Zn-0.8Li-0.2Ag(wt%) alloy as candidates for biodegradable materials. The biodegradable behavior of Zn-0.8Li-0.2Ag alloy in different solutions (Ringer's, DMEM, SBF and DMEMp) was investigated. The cytotoxicity of Zn-0.8Li-0.2Ag alloy and its antibacterial properties against staphylococcus aureus, enterobacter faecalis and candida albicans were evaluated. The results showed that Zn-0.8Li-0.2Ag alloy consists of zinc matrix and a LiZn 4 secondary phase. The presence of Cl − causes locally corroded of Zn-0.8Li-0.2Ag alloy in Ringer's solution, and its corrosion resistance is lower than that of the alloy which is uniformly corroded in other solutions containing CO 3 2− and PO 4 3− . Zn-0.8Li-0.2Ag alloy is non-toxic and exhibits better antibacterial properties than the experimental reference group without silver.

Zinc is emerging as a promising biodegradable metal for temporary implant applications. In this work, we investigate the influence of bovine serum albumin (BSA)-the most abundant blood protein in simulated body fluid (SBF) on degradation of pure Zn via electrochemical measurements and long-term immersion. Electrochemical experiments indicate a decrease of the corrosion rate of bare Zn with increasing BSA concentration in solution for short-term exposures. Samples were characterized with scanning electron microscope (SEM) (including energy dispersive spectroscopy [EDS], X-ray photoelectron spectroscopy [XPS], Fourier transform infrared spectroscopy [FTIR], and time-of-flight secondary ion mass spectrometry [TOF-SIMS]) after immersion up to 21 days. Presence of BSA in the electrolyte, decrease the amount of Caphosphate precipitation on Zn surface. However, a more compact surface layer formed in the presence of BSA in solution. Most noteworthy, in long-term exposures, BSA enhances localized corrosion of Zn-such detrimental localized attack was not observed in BSA-free solution. We suggest that a sealed space forming between the Zn substrate and a protein adsorption layer restricts mass transport, thus triggering localized corrosion of Zn.
