The effect of HAP and Al 2 O 3 composition with constant of ceramic content of 15 wt. % on mechanical properties, microstructure, and corrosion behavior of degradable Mg-Zn/HAP/Al 2 O 3 hybrid composite developed by powder metallurgy method were investigated. The microstructure was analyzed using an optical microscope and scanning electronic microscope while mechanical properties were evaluated for density and compression strength. Meanwhile, corrosion behavior in Hank Balanced salt solution (HBSS) was studied for 4 h. The addition of HAP and Al 2 O 3 particles has improved the mechanical properties and corrosion properties of Mg-Zn alloy. The results show that 15 wt. % Al 2 O 3 (without HAP) shows the higher density, hardness, and compression. However, the composite consisted of 10 wt. % HAP with 5 wt. % Al 2 O 3 shows the lower corrosion rate.
