Zn-based alloys (Zn) with control of the production process have the potential to give rise to a wide range of properties required for use in short-term implants. For this purpose, in the present study, a Zn-4wt%Mn alloy was prepared by mechanical alloying in three times of 10, 20 and 30 hours. Then some blocks were made by Spark plasma sintering (SPS) process. Heat treatment of manufactured parts was performed at three temperatures of 150, 200 and 250 ° C. The samples were characterized using XRD, dynamic polarization corrosion test and MTT cell viability evaluation. Also, the surface morphology of the samples was determined using scanning electron microscopy (SEM). The results showed that increasing the milling time to 30 hours created a more homogeneous composition, and the heat treated sample at 250 ° C had the highest corrosion resistance. Cell viability of the heat treated samples at this temperature showed higher viability than other samples. The results of this study are expected to be used in short-term implants.
