This study was aimed at improving the degradation rate and bioactivity of magnesium alloy by homogenization annealing and hydroxyapatite coating via electrophoretic approach. Hydroxyapatite was synthesized using co-precipitation method and deposited on mechanical treated and homogenized magnesium alloy. The characterization was done using optical microscope (OP), scanning electron microscope (SEM), transmission electron microscope (TEM), energy dispersive spectroscope (EDS), Fourier transform infrared spectroscope (FTIR). Homogeneous solution of hydroxy suspension was obtained by performing zeta potential measurement, and in-vitro bioactivity evaluation will be carried out in stimulated body fluid for 28 days. It is our expectation that a significant improvement would be recorded in controlling the degradation rate and in vitro evaluation of this alloy.
