## 3 Results and Discussion
### Biocorrosion Study  
The corrosion behavior of magnesium-based implants was investigated by analyzing corrosion potential, corrosion current, and biocorrosion after in vivo implementation. The electrochemical behavior of the samples was determined through corrosion potential and corrosion current measurements (Table 8). In particular, the effects of different anodization treatments (varying voltage levels and the incorporation of amino acids like lysine into the electrolytes) on the corrosion resistance of magnesium implants were analyzed (Figures 12 and 13). \begin{table}

Table 8: The obtained results of the corrosion potential and current values for the tested samples. Figure 12: The obtained values of corrosion potentials for each sample. Figure 13: The obtained values of corrosion current for individual samples. The analysis of the corrosion potential values indicated that the application of low voltages during anodic oxidation (e.g., for samples Mg_7-Mg_11) did not yield satisfactory results. These samples showed less uniform surface coverage, suggesting that the anodizing process was not optimized at lower voltages. However, after increasing the voltage, uniform surface coverage was observed, significantly enhancing the corrosion resistance of the implants. This finding suggests that higher voltages result in more effective oxide layer formation, which is critical for improving the durability and performance of magnesium implants in aggressive in vivo environments. Regarding the corrosion current, the best results were achieved for samples Mg_7, Mg_10-Mg_13, and Mg_17, where low corrosion current values were recorded, indicating slower degradation. This was consistent with the findings that higher voltage applications resulted in better corrosion protection. Conversely, low voltage applications led to higher corrosion current values, which corresponded to an increased degradation rate, a common concern when magnesium is used as a material for biodegradable implants.
