“…However, other studies have found significant influence of micro-galvanic cells on the corrosion process of the same system [ 39 , 40 ]. Similar inconsistencies can also be observed in the case of the formation of different corrosion products (complex Zn compounds, PO 4 3− based compounds) [ [40] , [41] , [42] , [43] ]. The differences in results between the individual studies may also be attributed to variations in the experimental conditions (such as composition [ 44 ] and temperature of the SBF [ 45 , 46 ]) or neglecting the initial state of the material surface before exposure.…”

“…There is a region of active dissolution at low overpotentials. This is followed by a deceleration of corrosion current at high overpotentials, likely indicating the occurrence of pseudo-passivity related to the formation of a surface film . There was minimal difference between the anodic Tafel slope value of Zn in S1 and those seen for Zn in the other solutions, where values range between 34 and 52 mV/dec.…”

The cathodic reaction, which is related to the oxygen reduction reaction (ORR), appears to determine the corrosion rate of Zn in the different solutions.…”

This work presents a study on the influence of biologically relevant ions on the corrosion of zinc (Zn) in physiological fluids. Electrochemical techniques were used to investigate the degradation of pure Zn exposed to different physiological electrolytes containing chlorides, carbonates, sulfates, and phosphates. The corrosion behavior of Zn in the solutions over a 7-day period was also assessed. SEM, EDS, and FTIR were used to analyze corrosion products. With respect to corrosion, the most aggressive ions are chlorides, which induce localized corrosion, while carbonates and phosphates reduce the corrosive attack of the chloride on Zn while inducing uniform corrosion. Sulfates reduce the corrosion rate by disrupting Zn’s passive layer. The overall corrosion rate of Zn changed in each electrolyte depending on the nature of the solution and the corrosion product formed. These findings will be useful in predicting the in-service behavior of future biodegradable Zn medical implants.

“…Generally, in the corrosion mechanism of metal-based biodegradable devices, the metals are oxidized into cations and H 2 , hydroxides, and oxides are produced by electrochemical reactions [ 52 , 53 , 54 ]. Finally, the metal oxide layer is formed on the surface of biodegradable metals, which acts as a kinetic barrier or passive layer and prevents the further electrochemical reaction or release of ions across the substrate’s surface [ 53 , 55 ]. However, this metal oxide layer can be dissolved in the electrolyte, and the pitting corrosion process starts after it [ 56 , 57 ].…”

Zn-based biodegradable alloys or composites have the potential to be developed to next-generation orthopedic implants as alternatives to conventional implants to avoid revision surgeries and to reduce biocompatibility issues. This review summarizes the current research status on Zn-based biodegradable materials. The biological function of Zn, design criteria for orthopedic implants, and corrosion behavior of biodegradable materials are briefly discussed. The performance of many novel zinc-based biodegradable materials is evaluated in terms of biodegradation, biocompatibility, and mechanical properties. Zn-based materials perform a significant role in bone metabolism and the growth of new cells and show medium degradation without the release of excessive hydrogen. The addition of alloying elements such as Mg, Zr, Mn, Ca, and Li into pure Zn enhances the mechanical properties of Zn alloys. Grain refinement by the application of post-processing techniques is effective for the development of many suitable Zn-based biodegradable materials.
