“…This is mainly due to the preferred orientation of the grains, the close arrangement between each crystal, the epitaxial growth in the crystallization direction, and the different growth directions. 44 When the electrodeposition temperature is extended to 30 °C (Fig. 2c and d), the surface morphology of the films changes from polyhedron shape like roses to small cauliflower-like clusters, and the size of the micropores is still variable.…”

“…In HCP crystal, basal planes are relatively more inert to corrosion than other planes. [ 20 ] Consequently, Zn‐0.4Gd alloy is least affected by intergranular corrosion considering its stronger basal texture. Although the second phase appears after adding Gd, the potential of GdZn 12 is close to Zn regarding Gd's low content, indicating a limited effect on galvanic corrosion.…”

Zinc (Zn) shows a great potential as a biodegradable material for bone implants after a decade of systematic research and development. However, uncontrollable biodegradation behavior and biphasic dose-response prevent Zn from fulfilling its essential role in facilitating bone regeneration. In this study, the low addition of gadolinium (Gd) modifies the intrinsic microstructure of Zn in terms of grain size distribution, grain boundary misorientation, and texture. Adding Gd refines grain size distribution and creates a stronger basal plane texture in Zn, consequently, changing the current density distribution and reducing the anode dissolution rate during corrosion. As a result, uniform degradation is more predominant in Zn-0.4Gd alloy implant, in comparison to localized degradation in pure Zn implant in bone environments. The modified biodegradation behavior of the Zn-0.4Gd alloy implant induces significantly better new bone formation and osseointegration compared to the pure Zn implant. Therefore, Gd with trace amounts is able to tune the degradation behavior and improve the performance of Zn-based implants in promoting bone regeneration.

“…For example, corrosion current densities in various Tafel studies (one of the most critical parameters in corrosion analysis) are reported as low as a few milliamperes per square to a few thousand milliamperes per centimeter square in various studies for Zn surfaces tested in 3.5 wt.% NaCl solution at 25 o C is presented in Table 1.

Tafel analysis is a widely accepted technique for corrosion studies in electrochemistry. A general literature search for one of the electronegative metals, zinc, revealed serious deviations in corrosion results. In order to understand the reasons behind these deviations, zinc metal was investigated at macro and micro levels during and after the Tafel corrosion analysis. In-situ macro surface investigation during the OCP period and Tafel analysis were performed, and it was found that the zinc surface undergoes proceeding corrosion attack following the immersion in 3.5 wt.% NaCl solution. In-situ macro surface analysis exhibited that the pre-oxidation of the surface proceeds as nonuniform at local regions. SEM-EDS and XRD analysis proved that the particular crystal planes of the zinc form ZnO with increasing immersion time. A linear sweep voltammetry (LSV) technique was applied to detect the oxygen removal and starting hydrogen evolution potentials. Three identical Tafel experiments were performed on samples without any treatment, and another three consecutive Tafel experiments were performed on the samples which applied pre-reduction potential. Obtained results revealed that in-situ pre-applied reduction potential just before the Tafel analysis cleaned the surface and allowed uniform oxide formation, resulting in the lowest standard deviation of the calculated Tafel elements.
