Zinc-based biodegradable materials have gained a considerable amount of attention recently [1,2]. Ideal degradation behaviour under physiological conditions and the suitable degradation rate and superior biocompatibility make these materials the most promising candidates for further clinical use [3]. Bone-like mechanical properties with interconnected pores are especially important in the case of those to be used as orthopedic scaffolds [4].

Several methods are currently used to prepare zinc-based degradable materials (e.g., additive manufacturing, gravity casting, and infiltration casting). In this work, space holder technique was used to prepare porous zinc-based materials. For the potential application as biodegradable bone implants, the changes in the compressive and corrosion properties of zinc foams were investigated with changing pore size. The effect of the relative density on the compressive behaviour and degradation properties was also studied.
