Magnesium (Mg) has a great potential to be used in various field of work since it is lightweight and has low density properties. However, its application is limited due to its poor properties for Mg has a relatively low strength. Improvement is made by mixing Mg with calcium (Ca) as composite element for it is lightweight and non-toxic. In this research, Mg is prepared with different weight percentage (0, 0.5, 1, 1.5, 2 wt. %) of Ca with pure Mg as reference prepared by powder metallurgy (PM) method to study the mechanical properties. Morphological analysis carried out by optical microscope shows increase grain refinement with the increase of calcium content in Mg-Ca composites. The phase transition upon addition of Ca is determined using XRD method detects formation of Mg2Ca. Range from 1.78 g/cm3to 1.83 g/cm3, the density of each sample composite increase. While porosity profiles show inverse characteristics upon addition of Ca. Microhardness strengths also intensifies up to 193.20 MPa as more Ca content added in.

(HAp/SiO2)/Ti biocomposites were prepared by the powder metallurgy method. The phase compositions and the in vitro bioactivity of such biocomposites were systematically characterized. The XRD result shows that the phase compositions of (HAp/SiO2)/Ti composites are mainly composed of Ca4O(PO4)2 (TTCP), Ti, TiO2 and CaO. The synthesized (HAp/SiO2)/Ti biocomposites exhibit a good bioactivity, for example, after the samples are immersed in SBF solution only for 24 hours, the bone-like layer consisting of spherical apatite crystal clusters has deposited on the surface of the samples. The density and thickness of the apatite layer increases with increasing immersion time. The formation process and mechanisms of bone-like apatite layer are also discussed.
