The utilization of Sn-Zn based solder on electronic product was only feasible if the corrosion performance of this solder was assured. To achieve this, micro-alloying eutectic Sn-9Zn with Al was proposed. The corrosion performance was evaluated by using potentiodynamic polarization in 1 M HCl at constant scan rate. The microstructure changes due to corrosion exposure was also investigated to further understand the corrosion behaviour changes due to additions of Al. Overall corrosion rate was reduced with the micro-alloying process. Refinement of Zn-rich phase was found to help in producing much lower corrosion current and better passivation film formation on the surface due to the additions of Al. This modification deemed promising and further work should be explored in the future.

Zinc (Zn) and its alloys, as novel biodegradable metals, hold great potential in bone implant and metallic stents. Stannum (Sn), an essential trace element, plays an important role in maintaining life activities. Herein, Sn is selected as an alloying element to be added into the Zn matrix to explore the possibility of Zn–Sn alloy as a biodegradable metal for clinical application. This article systemically studies the effects of Sn content on microstructural, electrochemical behavior, corrosion rate, and in vitro biocompatibility of Zn–Sn alloys. Results indicate that the Sn‐rich phase is the main form of Sn in the as‐extruded alloys, and the solid solubility is in an extremely minute quantity. The corrosion of Zn–Sn alloys in conventional simulated body fluid (c‐SBF) solution shows apparent electrochemical characteristics, and Sn‐rich phases are corroded preferably. The corrosion rates of Zn–1.0Sn and Zn–2.0Sn are under 0.2 mm year−1, which can satisfy the requirement of biodegradable medical materials. In addition, Zn–1.0Sn exhibits much better cytocompatibility and hemocompatibility than Zn–2.0Sn. Therefore, Zn–Sn alloy shows great potential applications in the biological field and can be further studied and developed.
