Abstract

Biomedical zinc (Zn) alloys are popular biomaterials due to their biodegradability and biocompatibility. Their corrosion behavior in physiological environments is influenced by factors such as ions, proteins, dissolved oxygen, and flow fields. The amount of dissolved oxygen (DO), which constitutes an important physiological condition, plays a key role in the corrosion of Zn alloys through oxygen-consuming processes. However, the specific impact of DO on the degradation of Zn alloys is not well understood. Herein, two different Zn alloys (Zn-0.16Cu and Zn-0.23Mg) are immersed in simulated body fluids (SBF) with different DO concentrations. In normal SBF, Zn-0.16Cu undergoes pitting corrosion due to galvanic corrosion, while Zn-0.23Mg experiences intergranular corrosion and shows good corrosion resistance, because preferential corrosion of the Mg₂Zn₁₁ second phase at grain boundaries requires a smaller corrosion potential than Zn. A larger DO concentration accelerates reduction and oxidation consequently promoting oxygen-consumption corrosion of the Zn alloys. Besides, the local difference in the DO concentration resulting from the accumulation of corrosion products leads to occluded cell corrosion and produces autocatalytic effects. This work provides experimental data and a theoretical basis guiding the clinical application of biodegradable Zn-based alloys.
