Abstract As-cast Zn-1Al alloy was fabricated with commercially pure zinc and pure aluminum as raw materials. Microstructure of the as-cast Zn-1Al alloy was observed by optical microscopy and scanning electron microscopy, and the compressive mechanical properties were measured by a universal test machine. The biodegradable property and the ability to induce Ca-P precipitation of the as-cast Zn-1Al alloy were characterized by immersion tests in simulated body fluid. The results show that the microstructures of the as-cast Zn-1Al alloy were obviously refined by adding 1wt% Al element. In addition, the compressive mechanical properties of the as-cast Zn-1Al alloy were also enhanced compared with that of as-cast pure zinc. The immersion tests in simulated body fluid suggest that the as-cast Zn-1Al alloy has a similar degradable rate compared to as-cast pure Zn. However, Zn-1Al alloy can more efficiently induce Ca-P precipitation during immersion tests.

Key words： Zn-1Al alloy mechanical property Ca-P precipitation biomedical application degradability
