Table 2 gives the chemical composition of the as-cast  Mg-xCa alloys. It can be seen that the calcium percentage  of the as-cast alloys follows the nominal composition of  the alloys indicating acceptable casting procedure
Table 3. The average grain diameter of pure Mg and as-cast Mg-Ca alloys.
Figure 8 illustrates the increase in pH values of  SBF for all tested samples for the whole duration of the  immersion test, although the rate of pH value changes  gradually decreased over time
